get an element's id
JavascriptHtmlJavascript Problem Overview
Is there another way to get an DOM element's ID?
element.getAttribute('id')
Javascript Solutions
Solution 1 - Javascript
Yes you can just use the .id property of the dom element, for example:
myDOMElement.id
Or, something like this:
var inputs = document.getElementsByTagName("input");
for (var i = 0; i < inputs.length; i++) {
alert(inputs[i].id);
}
Solution 2 - Javascript
Yes you can simply say:
function getID(oObject)
{
var id = oObject.id;
alert("This object's ID attribute is set to "" + id + "".");
}
Check this out: ID Attribute | id Property
Solution 3 - Javascript
This would work too:
document.getElementsByTagName('p')[0].id
(If element where the 1st paragraph in your document)
Solution 4 - Javascript
Super Easy Way is
$('.CheckBxMSG').each(function () {
var ChkBxMsgId;
ChkBxMsgId = $(this).attr('id');
alert(ChkBxMsgId);
});
Tell me if this helps
Solution 5 - Javascript
In events handler you can get id as follows
function show(btn) {
console.log('Button id:',btn.id);
}
<button id="myButtonId" onclick="show(this)">Click me</button>
Solution 6 - Javascript
You need to check if is a string to avoid getting a child element
var getIdFromDomObj = function(domObj){
var id = domObj.id;
return typeof id === 'string' ? id : false;
};
Solution 7 - Javascript
This gets and alerts the id of the element with the id "ele".
var id = document.getElementById("ele").id;
alert("ID: " + id);
Solution 8 - Javascript
Yes. You can get an element by its ID by calling document.getElementById. It will return an element node if found, and null otherwise:
var x = document.getElementById("elementid"); // Get the element with id="elementid"
x.style.color = "green"; // Change the color of the element
