<div id="addEdgeModal" class="modal hide fade">
  <div class="modal-body">
    <form class="form-horizontal">    
<div class="control-group">
    <div class="controls">
      <textarea rows="3"></textarea>

  </div>


<script>
       $("#addEdgeModalB").on("click",function(e){
           alert("click");
           $("addEdgeModal").modal("show"); 
        });
</script>

Answer 1

Try,

$("[href='#addEdgeModalB']").on("click",function(e){
   alert("click");           
});

There is no id there for using id selector here. Use attribute equals selector at this context.

});
