Is it ok to get the value of a textarea element in JavaScript with `myTextArea.value` or should I use `myTextArea.innerHTML`?

Thank you.

JavaScript get TextArea input via .value or .innerHTML?

Difference between innerText, innerHTML and value?

I have a php generated list whose list items are selectable using jquery selectable widget. The list for all intents and purposes is:

    &lt;ul id=&quot;#select-image&quot;&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 1&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 2&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 3&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 4&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 5&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 6&lt;/li&gt;
        &lt;li class=&quot;ui-widget-content&quot;&gt;Item 7&lt;/li&gt;
    &lt;/ul&gt;

And the jQuery selectable is declared as:

    &lt;script&gt;
        $(function() {
            $(&quot;#select-image&quot;).selectable({
                selected: function( event, ui ) { 
                    var $variable = $(&#39;.ui-selected&#39;).innerHTML; 
                    console.log($variable);
                }
            });
        });
    &lt;/script&gt;

An event takes place after a list item has been selected, in the example it outputs to the browser console. The output however is &quot;undefined.&quot; The selector `$(&#39;.ui-selected&#39;).` is correct as it shows as an object in the browser&#39;s console. Where am I going wrong?

How to get the innerHTML of selectable jquery element?

How could I achieve the following:

How to replace innerHTML of a div using jQuery?

Is there any &quot;behind the scenes&quot; difference from setting an element&#39;s innerHTML vs setting the dangerouslySetInnerHTML property on an element? Assume I&#39;m properly sanitizing things for the sake of simplicity.

Example:

    var test = React.createClass({
      render: function(){
        return (
          &lt;div contentEditable=&#39;true&#39; dangerouslySetInnerHTML={{ __html: &quot;Hello&quot; }}&gt;&lt;/div&gt;
        );
      }
    });


vs

    var test = React.createClass({
      componentDidUpdate: function(prevProp, prevState){
        this.refs.test.innerHTML = &quot;Hello&quot;;
      },
      render: function(){
        return (
          &lt;div contentEditable=&#39;true&#39; ref=&#39;test&#39;&gt;&lt;/div&gt;
        );
      }
    });
&lt;div contentEditable=&#39;true&#39; ref=&#39;test&#39;&gt;&lt;/div&gt;

I&#39;m doing something a bit more complicated than the above example, but the overall idea is the same

React.js: Set innerHTML vs dangerouslySetInnerHTML

I tried to load some scripts into a page using `innerHTML` on a `&lt;div&gt;`. It appears that the script loads into the DOM, but it is never executed (at least in Firefox and Chrome). Is there a way to have scripts execute when inserting them with `innerHTML`?

Sample code:

    

&lt;!-- begin snippet: js hide: false --&gt;

&lt;!-- language: lang-html --&gt;

    &lt;!DOCTYPE html&gt;
    &lt;html&gt;
      &lt;body onload=&quot;document.getElementById(&#39;loader&#39;).innerHTML = &#39;&lt;script&gt;alert(\&#39;hi\&#39;)&lt;\/script&gt;&#39;&quot;&gt;
        Shouldn&#39;t an alert saying &#39;hi&#39; appear?
        &lt;div id=&quot;loader&quot;&gt;&lt;/div&gt;
      &lt;/body&gt;
    &lt;/html&gt;

&lt;!-- end snippet --&gt;



Can scripts be inserted with innerHTML?

For a website I&#39;m doing, I want to load one div, and hide another, then have two buttons that will toggle views between the div using JavaScript.

**This is my current code**

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-js --&gt;

    function replaceContentInContainer(target, source) {
      document.getElementById(target).innerHTML = document.getElementById(source).innerHTML;
    }

    function replaceContentInOtherContainer(replace_target, source) {
      document.getElementById(replace_target).innerHTML = document.getElementById(source).innerHTML;
    }

&lt;!-- language: lang-html --&gt;

    &lt;html&gt;
    &lt;button onClick=&quot;replaceContentInContainer(&#39;target&#39;, &#39;replace_target&#39;)&quot;&gt;View Portfolio&lt;/button&gt;
    &lt;button onClick=&quot;replaceContentInOtherContainer(&#39;replace_target&#39;, &#39;target&#39;)&quot;&gt;View Results&lt;/button&gt;

    &lt;div&gt;
      &lt;span id=&quot;target&quot;&gt;div1&lt;/span&gt;
    &lt;/div&gt;

    &lt;div style=&quot;display:none&quot;&gt;
      &lt;span id=&quot;replace_target&quot;&gt;div2&lt;/span&gt;
    &lt;/div&gt;

&lt;!-- end snippet --&gt;

The second function that replaces div2 is not working, but the first one is.


Show/hide &#39;div&#39; using JavaScript

I need a way to append HTML to a container element without using innerHTML. The reason why I do not want to use innerHTML is because when it is use like this:

`element.innerHTML += htmldata`

It works by replacing all of the html first before adding the old html plus the new html. This is not good because it resets dynamic media such as embedded flash videos...

I could do it this way which works:

    var e = document.createElement(&#39;span&#39;);
    e.innerHTML = htmldata;
    element.appendChild(e);

However the problem with that way is that there is that extra span tag in the document now which I do not want.

How can this be done then? Thanks!

Javascript - Append HTML to container element without innerHTML

I am getting chunks of HTML codes from HTTP calls. I put the HTML blocks in a variable and insert it on my page with [innerHTML] but I can not style the inserted HTML block. Does anyone have any suggestion how I might achieve this?

 &lt;!-- language: lang-typescript --&gt;

    @Component({
      selector: &#39;calendar&#39;,
      template: &#39;&lt;div [innerHTML]=&quot;calendar&quot;&gt;&lt;/div&gt;&#39;,
      providers: [HomeService], 
      styles: [`h3 { color: red; }`]
    })

The HTML that I want to style is the block contained in the variable &quot;calendar&quot;. 


Angular 2 - innerHTML styling

I&#39;ve got a script that inserts some content into an element using `innerHTML`.

The content could for example be:

    &lt;script type=&quot;text/javascript&quot;&gt;alert(&#39;test&#39;);&lt;/script&gt;
    &lt;strong&gt;test&lt;/strong&gt;

Problem is that the code inside the `&lt;script&gt;` tag doesn&#39;t get executed.
I googled it a bit but there were no apparent solutions. If I inserted the content using jQuery `$(element).append(content);`the script parts got `eval`&#39;d before being injected into the DOM.

Has anyone got a snippet of code that executes all the `&lt;script&gt;` elements? The jQuery code was a bit complex so I couldn&#39;t really figure out how it was done.

**Edit**:

By peeking into the jQuery code I&#39;ve managed to figure out how jQuery does it, which resulted in the following code:

    Demo:
    &lt;div id=&quot;element&quot;&gt;&lt;/div&gt;
    
    &lt;script type=&quot;text/javascript&quot;&gt;
      function insertAndExecute(id, text)
      {
        domelement = document.getElementById(id);
        domelement.innerHTML = text;
        var scripts = [];
      
        ret = domelement.childNodes;
        for ( var i = 0; ret[i]; i++ ) {
          if ( scripts &amp;&amp; nodeName( ret[i], &quot;script&quot; ) &amp;&amp; (!ret[i].type || ret[i].type.toLowerCase() === &quot;text/javascript&quot;) ) {
      			scripts.push( ret[i].parentNode ? ret[i].parentNode.removeChild( ret[i] ) : ret[i] );
      		}
        }
      
        for(script in scripts)
        {
          evalScript(scripts[script]);
        }
      }
      function nodeName( elem, name ) {
      	return elem.nodeName &amp;&amp; elem.nodeName.toUpperCase() === name.toUpperCase();
      }
      function evalScript( elem ) {
      	data = ( elem.text || elem.textContent || elem.innerHTML || &quot;&quot; );
    
        var head = document.getElementsByTagName(&quot;head&quot;)[0] || document.documentElement,
      	script = document.createElement(&quot;script&quot;);
      	script.type = &quot;text/javascript&quot;;
      	script.appendChild( document.createTextNode( data ) );
      	head.insertBefore( script, head.firstChild );
      	head.removeChild( script );
    
      	if ( elem.parentNode ) {
      		elem.parentNode.removeChild( elem );
      	}
      }
    
      insertAndExecute(&quot;element&quot;, &quot;&lt;scri&quot;+&quot;pt type=&#39;text/javascript&#39;&gt;document.write(&#39;This text should appear as well.&#39;)&lt;/scr&quot;+&quot;ipt&gt;&lt;strong&gt;this text should also be inserted.&lt;/strong&gt;&quot;);
    &lt;/script&gt;

Executing &lt;script&gt; elements inserted with .innerHTML

I&#39;m using plain js to alter the inner text of a label element, and I wasn&#39;t sure on what grounds I should use innerHTML or nodeValue or textContent. I don&#39;t need to create a new node or change the HTML elements or anything —&#160;just replace the text. Here&#39;s an example of the code:

    var myLabel = document.getElementById(&quot;#someLabel&quot;);
    myLabel.innerHTML = &quot;Some new label text!&quot;; // this works

    myLabel.firstChild.nodeValue = &quot;Some new label text!&quot;; // this also works.
 
    myLabel.textContent = &quot;Some new label text!&quot;; // this also works.

I looked through the jQuery source, and it uses nodeValue exactly one time but innerHTML and textContent several times. Then I found this jsperf test that indicates the firstChild.nodeValue is significantly faster. At least that&#39;s what I interpret it to mean. 

If firstChild.nodeValue is so much faster, what&#39;s the catch? Is it not widely supported? Is there some other issue?

nodeValue vs innerHTML and textContent. How to choose?

In the following example code, I attach an `onclick` event handler to the span containing the text &quot;foo&quot;. The handler is an anonymous function that pops up an `alert()`.

However, if I assign to the parent node&#39;s `innerHTML`, this `onclick` event handler gets destroyed - clicking &quot;foo&quot; fails to pop up the alert box.

Is this fixable?

    &lt;html&gt;
     &lt;head&gt;
     &lt;script type=&quot;text/javascript&quot;&gt;
    
      function start () {
        myspan = document.getElementById(&quot;myspan&quot;);
        myspan.onclick = function() { alert (&quot;hi&quot;); };
    
        mydiv = document.getElementById(&quot;mydiv&quot;);
        mydiv.innerHTML += &quot;bar&quot;;
      }
    
     &lt;/script&gt;
     &lt;/head&gt;
    
     &lt;body onload=&quot;start()&quot;&gt;
       &lt;div id=&quot;mydiv&quot; style=&quot;border: solid red 2px&quot;&gt;
         &lt;span id=&quot;myspan&quot;&gt;foo&lt;/span&gt;
       &lt;/div&gt;
     &lt;/body&gt;
    
    &lt;/html&gt;


Is it possible to append to innerHTML without destroying descendants&#39; event listeners?

Why do I get an error or Uncaught TypeError: Cannot set property &#39;innerHTML&#39; of null?
I thought I understood innerHTML and had it working before.

    &lt;!DOCTYPE HTML&gt;
    &lt;html&gt;
    &lt;head&gt;
    &lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=UTF-8&quot;&gt;
    &lt;title&gt;Untitled Document&lt;/title&gt;

    &lt;script type =&quot;text/javascript&quot;&gt;
        what();
        function what(){
            document.getElementById(&#39;hello&#39;).innerHTML = &#39;hi&#39;;
        };
    &lt;/script&gt;

    &lt;/head&gt;
    
    &lt;body&gt;
    &lt;div id=&quot;hello&quot;&gt;&lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;

Cannot set property &#39;innerHTML&#39; of null

I&#39;m attempting to add this code to a dynamically created div element

    style = &quot;width:330px;float:left;&quot; 

The code in which creates the dynamic `div` is 

    var nFilter = document.createElement(&#39;div&#39;);
    nFilter.className = &#39;well&#39;;
    nFilter.innerHTML = &#39;&lt;label&gt;&#39; + sSearchStr + &#39;&lt;/label&gt;&#39;;

My idea is to add the style after `&lt; div class=&quot;well&quot;` but i don&#39;t know how i&#39;d do it. 

Add inline style using Javascript

Why doesn&#39;t the following work for me?

Change label text using JavaScript

What function do you use to get innerHTML of a given DOMNode in the PHP DOM implementation? Can someone give reliable solution? 

Of course outerHTML will do too.

How to get innerHTML of DOMNode?

I want to be able to add multiple rows to a div and also removing them. I have a &#39;+&#39; button at the top of the page which is for adding content. Then to the right of every row there is a &#39;-&#39; button that&#39;s for removing that very row. I just can&#39;t figure out the javascript code in this example.

**This is my basic HTML structure:**

    &lt;input type=&quot;button&quot; value=&quot;+&quot; onclick=&quot;addRow()&quot;&gt;
    					
    &lt;div id=&quot;content&quot;&gt;
    
    &lt;/div&gt;
**This is what I want to add inside the content div:**

    &lt;input type=&quot;text&quot; name=&quot;name&quot; value=&quot;&quot; /&gt;
    &lt;input type=&quot;text&quot; name=&quot;value&quot; value=&quot;&quot; /&gt;
    &lt;label&gt;&lt;input type=&quot;checkbox&quot; name=&quot;check&quot; value=&quot;1&quot; /&gt;Checked?&lt;/label&gt;
    &lt;input type=&quot;button&quot; value=&quot;-&quot; onclick=&quot;removeRow()&quot;&gt;

Add/remove HTML inside div using JavaScript

Can I completely rely upon jQuery&#39;s `html()` method behaving identical to `innerHTML`? Is there any difference between `innerHTML` and jQuery&#39;s `html()` method? If these methods both do the same, can I use jQuery&#39;s `html()` method in place of `innerHTML`?

My problem is: I am working on already designed pages, the pages contains tables and in JavaScript the `innerHTML` property is being used to populate them dynamically.

The application is working fine on *Firefox* but *Internet Explorer* fires an error: `unknown runtime exception`. I used jQuery&#39;s `html()` method and *IE*&#39;s error has disappeared. But I&#39;m not sure it will work for all browsers and I&#39;m not sure whether to replace all `innerHTML` properties with jQuery&#39;s `html()` method.

Thanks a lot.


JQuery html() vs. innerHTML

In practice, what are the advantages of using createElement over innerHTML? I am asking because I&#39;m convinced that using innerHTML is more efficient in terms of performance and code readability/maintainability but my teammates have settled on using createElement as the coding approach. I just wanna understand how createElement can be more efficient. 

Advantages of createElement over innerHTML?

Let&#39;s say I have a page with a `div`. I can easily get that div with `soup.find()`.

Now that I have the result, I&#39;d like to print the WHOLE `innerhtml` of that `div`: I mean, I&#39;d need a string with ALL the html tags and text all toegether, exactly like the string I&#39;d get in javascript with `obj.innerHTML`.  Is this possible?


BeautifulSoup innerhtml?

I have been told not to append stuff using `element.innerHTML += ...` like this:

    var str = &quot;&lt;div&gt;hello world&lt;/div&gt;&quot;;
    var elm = document.getElementById(&quot;targetID&quot;);
    
    elm.innerHTML += str; //not a good idea?

What is wrong with it?, what other alternatives do I have?

Why is &quot;element.innerHTML+=&quot; bad code?

I&#39;m trying to clear the div&#39;s innerHTML before repopulating it.  I tried removeData() but once that&#39;s called, when I try to add the data, I get nothing from the next line after remove whereas if I remove the removeData() it&#39;s fine again.  I just want to clear out any previous content in that div before I re-populate it.

        divToUpdate.removeData(); //clean out any existing innerHTML div content first
        divToUpdate.html(data);

It looks like it never gets to my divToUpdate.html(data) for some reason after it calls that removeData();
