javascript - Duplicating Div always duplicates -


to better understand question , see code visit fiddle: http://jsfiddle.net/dnyxc/

i have script (below) allows click icon , duplicates table allowing more inputs on included form. issue is, once click icon once duplicate it, anywhere click on table regardless of position duplicates table again. 

document.getelementbyid('line-duplicate').onclick = duplicate;     var = 0;          function duplicate() {             var original = document.getelementbyid('item-table' + i);             var clone = original.clonenode(true); // "deep" clone             clone.id = "item-table" + ++i; // there can 1 element id             clone.onclick = duplicate; // event handlers not cloned             original.parentnode.appendchild(clone);         }

here html table: 

<table class="table" id="item-table0"> <tr>     <td>item name</td>     <td>qty/hrs</td>     <td>rate</td>     <td>tax rate</td>     <td>type</td>     <td>cost</td>     <td>actions</td> </tr> <tr>     <td>         <input class="input-medium" type="text" name="" />     </td>     <td>         <input class="input-mini" type="text" name="" placeholder="1" />     </td>     <td>         <input class="input-mini" type="text" name="" placeholder="0.00" />     </td>     <td></td>     <td>         <select class="input-small" name="">             <option>standard</option>             <option>expense</option>         </select>     </td>     <td>$0.00</td>     <td><i class="icon-plus" style="cursor:pointer;" id="line-duplicate"></i>  <i class="icon-trash pull-right"></i>         </a>     </td> </tr>

endless duplication fine, issue when go type item form, duplicate table. need way duplicate table clicking plus icon.

the issue binding onclick entire duplicated row duplicate() function.

you should make line-duplicate class (having multiple elements same id bad thing), , use document.getelementsbyclassname('line-duplicate') both inside , outside function bind duplicate function every single element class name, so:

document.getelementsbyclassname('line-duplicate')[0].onclick = duplicate;  var = 0;  function duplicate() {     var original = document.getelementbyid('item-table' + i);     var clone = original.clonenode(true); // "deep" clone     clone.id = "item-table" + ++i; // there can 1 element id     original.parentnode.appendchild(clone);     var listoflineduplicateitems = document.getelementsbyclassname('line-duplicate'); // must after table has been appended dom     (var j = 0; j < listoflineduplicateitems.length; ++j) {         listoflineduplicateitems[i].onclick = duplicate;     } }

here's jsfiddle.
