Jquery Solutions
Solution 1 - Jquery
When you do $("#vinanghinguyen_images_bbocde").val('');
, it removes all the content of the textarea, so if that's not what is happening, the problem is probably somewhere else.
It might help if you post a little bit larger portion of your code, since the example you provided works.
Solution 2 - Jquery
Use $('textarea').val('')
.
The problem with using
$('textarea').text('')
, or
$('textarea').html('')
for that matter is that it will only erase what was in the original DOM sent by the server. If a user clears it and then enters new input, the clear button will no longer work. Using .val('')
handles the user input case properly.
Solution 3 - Jquery
This works:
$('#textareaName').val('');
Solution 4 - Jquery
try this
$("#vinanghinguyen_images_bbocde").attr("value", "");
Solution 5 - Jquery
> This method removes not only child (and other descendant) elements, > but also any text within the set of matched elements. This is because, > according to the DOM specification, any string of text within an > element is considered a child node of that element.
$('textarea').empty()
Solution 6 - Jquery
Try this,
$('textarea#textarea_id').val(" ");
Solution 7 - Jquery
I just tried using this code and @psynnott's answer was correct though I needed to know it would work repeatedly, seems to work with jquery 1.7.1 >
I modified the jfiddle to the following http://jsfiddle.net/Rjj9v/109/
$('#mytext').text('');
This is not a new answer @psynnott is correct I am just providing a more concise example that shows the textarea is still working after the clear because if you use .val("") the text area stops working
Solution 8 - Jquery
I believe the problem is simply a spelling error when writing bbcode as bbocde:
$("#vinanghinguyen_images_bbocde").val('')
should be:
$("#vinanghinguyen_images_bbcode").val('')
Solution 9 - Jquery
Rather simpler method would be by using JavaScript method of innerHTML.
document.getElementById("#id_goes_here").innerHTML = "";
Rather simpler and more effective way.
Solution 10 - Jquery
Correct answer is: $("#selElement_Id option:selected").removeAttr("selected");
Solution 11 - Jquery
I agree with @Jakub Arnold's answer. The problem should be somewhere else. I could not figure out the problem but found a work around.
Wrap your concerned element with a parent element and cause its html to create a new element with the id you are concerned with. See below
<div id="theParent">
<div id="vinanghinguyen_images_bbocde"></div>
</div>
'onSelect' : function(event,ID,fileObj) {
$("#theParent").html("<div id='vinanghinguyen_images_bbocde'></div>");
$("#vinanghinguyen_result").hide();
$(".uploadifyQueue").height(315);
}
