动态添加的锚点点击不调用jQuery Mobile中的功能

Question

My page fetches string data from local SQL and appends it to data-role='listview' as li using function below(simplified version)

function CreateListview{
   var temp ='<li><a href="#" class="anchor">String Here</a></li>';
   $("#<ul>-selector").append(temp).listview("refresh");
}

well, it works fine so I binded a click event for the anchor(class='.anchor')

$(document).on('vclick', '.anchor', function(e){
  e.preventDefault();
  alert("ANCHOR CLICKED");
});

OR

$(document).on('vclick', '#ul-selector > a', function(e){
  e.preventDefault();
  alert("ANCHOR CLICKED");
});

OR

$(document).on('vclick', '#ul-selector > li a', function(e){
  e.preventDefault();
  alert("ANCHOR CLICKED");
});

OR even

$(document).on('vclick', 'a', function(e){
  e.preventDefault();
  alert("ANCHOR CLICKED");
});

But nothing works I double-checked if click event on other elements works by using the function below on dynamically added li and it sometimes works and sometime doesn't.

I don't know why it works randomly,

but I checked that click events are fired on some other dynamically added elements.

$(document).on('vclick', '#ul-selector > li', function(e){
  alert("<li> CLICKED");
});

When it comes to binding click function to dynamically added anchors , the function won't be fired.. could it be a bug? or am I writing codes wrong?

Can you give me a working example binding click event to dynamically added anchor?

Answer 1

It seems works fine for me.

 function CreateListView() { var temp ='<li><a href="#" class="anchor">String Here</a></li>'; $("#selector").append(temp).listview("refresh"); } $(document).on('vclick', '.anchor', function(e){ e.preventDefault(); alert("ANCHOR CLICKED"); }); $("#createLi").on("vclick", function(){ CreateListView(); alert("test"); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.js"></script> <div id="content"> <ul id="selector"> </ul> </div> <input id="createLi" type="button" value="create li"/> 

Am I missing something?

bind the event after you append the html like this

function CreateListview{
   var temp ='<li><a href="#" class="anchor">String Here</a></li>';
   $("#<ul>-selector").append(temp).listview("refresh");

$("#<ul>-selector > li").on("click",function(){
 alert("<li> CLICKED");
});

}

check this fiddle you can apply the same logic here

You're not listening to the click event but vclick (???).

$("yourUl").on('click', '.anchor', function(e){
  e.preventDefault();
  alert("ANCHOR CLICKED");
});

I found the solution.

Problem : with cordova, 'click' on anchor doesn't fire function even with e.preventDefault(); Rather, 'touchstart' works fine.

Solution : 'click' -> 'touchstart' to work on devices

$(document).on('touchstart', '#anchor-selector', function(){
   alert("touch");
});
