ondblclick="return showCodeList 分析思路

  <Div id="divApproveRejectReasonInput" style="display:none">
<input class="CodeNo" name="RejectReason" verify="拒绝原因|Code:EdorRejectReason" 
ondblclick="return showCodeList('EdorRejectReason',[this,RejectReasonName],[0,1])" 
onkeyup="return showCodeListKey('EdorRejectReason',[this,RejectReasonName],[0,1])">
<input class="CodeName" name="RejectReasonName" readonly></Div>

f　思路

点击事件之后调用showCodeList()函数,此时要在CodeQueryBL中设置断点
