jquery bind plugin to live element

I have some input text fields that are being generated on the fly (via javascript) by the user. I want those fields to accept integers only so I am using the alphanumeric plugin. The plugin works as expected on elements that already e开发者_运维技巧xist when the page loads but it does not work with the new on-the-fly elements. How can I live-bind the new elements to this plugin? Thanks!

Here is some sample code.

Simple quick fix - change:

$('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" class="intonly" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv);

to

$('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" class="intonly" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').numeric().appendTo(scntDiv);

Please notice that the dynamically inserted fields are all getting the same id. That's not good, you should either use a unique id for each input, or no id at all.

Here you go

You just need this

$('#addScnt').live('click', function() {
                $('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" class="intonly" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv).find("input").numeric();

The issue is not because you are using live, its because you are not running the numberic plugin on the newly created input box.

live will not help you here. You'll have to re-initiate the plugin whenever you add a new input:

$('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" class="intonly" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>')
    .appendTo(scntDiv)
    .find('input').numeric();

One way is just to call the alphanumeric plugin for your dynamic inputs:

$('#addScnt').live('click', function() {
    $('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" class="intonly" name="p_scnt_' + i + '" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv);
    i++;
    $('#p_scents p:last input').numeric(); // Added this line...
    return false;
});

---

Just call the .numeric() method on the newly appended input field. After doing the .appendTo(scntDiv), you call:

scntDiv.children('p:last .intonly').numeric();
