Submit form via jQuery doesn't work

Question

I am trying to call a function when the form submit button is clicked. The page should not refresh, I want to add the category via AJAX.

The problem is that everything works fine when I add it manually to the html file, but when I try to add it in the javascript function via appendTo, the click function is never called. What is the problem here?

Javascript:

$(".addCategoryBtn").click(function() {  
       console.log('add category clicked');
    });  

Part of the JavaScript function:

html += '<br><br><form id="addCategory_form" action=""><input type="text" class="inptCategoryName" placeholder="Kategorie Name">&nbsp;<input type="text" class="inptHtmlColor" placeholder="Hintergrund: #000FFF">&nbsp;<input type="text" class="inptTextColor" placeholder="Text: #000FFF"><input type="button" value="Go" class="addCategoryBtn"></form></div>';

$(html).appendTo($('body'));

Answer 1

For dynamic content, when using jquery 1.7 or later, use on():

$("body").on('click','.addCategoryBtn',function() {  
    console.log('add category clicked');
});

For jQuery 1.6.x and lower, including 1.4.3 use delegate():

$("body").delegate('.addCategoryBtn', 'click', function() {  
   console.log('add category clicked');
}); 

For jQuery 1.4.2 or lower use bind after the append:

html += '<br><br><form id="addCategory_form" action=""><input type="text" class="inptCategoryName" placeholder="Kategorie Name">&nbsp;<input type="text" class="inptHtmlColor" placeholder="Hintergrund: #000FFF">&nbsp;<input type="text" class="inptTextColor" placeholder="Text: #000FFF"><input type="button" value="Go" class="addCategoryBtn"></form></div>';

$(html).appendTo($('body'));

$(".addCategoryBtn").bind("click", function() {  
    console.log('add category clicked');
}); 

Eitherway, what ever you do, try to avoid live()

Because dynamic content event must be bound using on function :

$("body").on('click','.addCategoryBtn',function() {  
       console.log('add category clicked');
});
