我在javascript中使用了此代码，但是我的问题是当ExperienceValidation()函数运行并且返回false时，请求仍在服务器端进行.请帮助我，并提前感谢

解决方案

当您从Button调用javascript时给出"返回"，请检查以下内容

 <   asp:button     id   ="     runat   =" 服务器" 文本  检查"  onclientclick   ="     xmlns:asp   ="  span> >  <  /asp:button  >  

您可以尝试使用OnClientClick

有关更多信息，请参见 http://msdn.microsoft.com/zh-cn/library/system.web.ui.webcontrols.button.onclientclick.aspx [<script language="javascript" type="text/javascript"> function JobDetailsValidation() { debugger; var Position=document.getElementById("txtPosition").value; var KeySkills=document.getElementById("txtKeySkills").value; var JobDescription=document.getElementById("txtJobDiscription").value; var JobLocation=document.getElementById("txtJobLocation").value; if(Position==null||Position==""||KeySkills==null||KeySkills==""||JobDescription==null||JobDescription==""||JobDescription==null||JobDescription==""||JobLocation==null||JobLocation=="") { alert("Job Details name must be filled out"); return false; } else { ExperienceValidation() } } function ExperienceValidation() { var Experience=document.getElementById("DropDownList1").value; var Experience1=document.getElementById("DropDownList2").value; var CTC=document.getElementById("DropDownList3").value; var Level=document.getElementById("DropDownList4").value; var Gender=document.getElementById("DropDownList5").value; if(Experience==null||Experience==""||Experience1==null||Experience1==""||CTC==null||CTC==""||Level==null||Level==""||Gender==null||Gender=="") { alert("Please Select All Details Of Experience Section"); return false; } return false; } </script>

I uses this code in javascript,but my problem is when the function ExperienceValidation() run and when it returns false the request is still going on the server side.Please help me and thanks in advance

解决方案

when you calling javascript from Button give "return" , check below

<asp:button id="btnOne" runat="server" text="check" onclientclick="return JobDetailsValidation()" xmlns:asp="#unknown"></asp:button>

You can try with OnClientClick

for more info see http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button.onclientclick.aspx[^]
