js用法收集2(失去焦点、获得焦点事件)

1.获得焦点则输入框中文字被选中

<html:textarea property="crmCmrSuccess" value="成功经验" name="<%=Constants.CRM_MARKET_RESULT%>" rows="2" style="width:100%;"onfocus="if(this.value=='成功经验') this.select();" /> 

 

2.失去焦点时进行有效性验证

<html:text name="details" property="crmCedPlanfee" onblur="calMoney();"styleClass="input_text_none" indexed="true" />   

 

<script language="javascript">

function calMoney(){
 var feeTotal = document.forms[0].elements("crmCetTotlemoney");
 var chks = document.forms[0].elements("chk");
 var allmoney = 0;
 var planfee ;
 
 for(var i=0;i<chks.length;i++){
  if(chks[i].checked == true){ 
   planfee = document.all("details[" + i + "].crmCedPlanfee");
   if(isNaN(planfee.value))
    planfee="0";
   allmoney += parseFloat(planfee.value);
  }
 }
 feeTotal.value = roundDecimal(allmoney,2);
}

</script>
