Using jQuery, I change the value of an input text field through some process. After the process is done, I need to capture this change and apply it to another process. My problem is that I can't seem to capture this change and assign it to a variable. I know the changes are happening because the DOM is getting updated. Furthermore, this variable assignment works in IE, but not for the other browsers I tested.
Below is a snippet to prove my point (and you can see this online here: http://jsfiddle.net/xMwAE/).
<form>
<input type="hidden" name="my_hidden" value="Hidden Field" />
<input type="text" name="my_text" value="Text Field" />
</form>
$().ready(function() {
$('input[name=my_hidden]').val('Hello Hidden Field');
$('input[name=my_text]').val('Hello Text Field');
// Display
var temp = $('form').html();
// Though the DOM is updated with the ne开发者_开发技巧w values. The variable temp
// does not capture the changes to the input text field, but captures
// the change in the hidden field. When in IE, temp captures the
// changes in both fields.
alert(temp);
});
Obviously, I need consistent behavior across browsers. Any ideas what's going on?
I don't get any trusted idea what happens, but somehow there should be a difference between setting the value as a member (input.value) or setting the value as a attribute-node.
This works for me :
$('input[name=my_text]').each(function()
{ this.setAttribute('value','Hello Text Field');});
I guess its a bug in innerHTML, see bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=535992
Alternatively, you can store the values of your fields into array and use however you like like this:
var data = [];
$('form :input').each(function(){
data.push(this.value);
});
Now you can check for values like this:
alert(data[0]);
alert(data[1]);
