jquery - javascript function containing ajax do not work after submit but work with button click event -


it strange. have function ajax works great:

function searchproduct(){ var barcode=$.trim($('#barcode1').val()); $.ajax({         type: 'get',         url: 'http://.............',         data:{              action: "search",              var: barcode,              },         cache: false,         datatype: 'json',         success: function(output){

when call function form submit event, way, error function of ajax. 

<form id="searchbox" name="searchbox" onsubmit="searchproduct()">

but if call function button click event works , success()

<span  class="tab-label" onclick="searchproduct()">scan</span>

what think this?

form submit send httprequest web server, wonder why want send ajax request along that.

onclick simple event can use trigger ajax request, not send other httprequest server.
