在asp.net调用javascript的步骤
第一步:在asp.net页面写javascript方法
放在<body><form>之间
<scriptlanguage="javascript"type="text/javascript">functionvalidate()
{
if(document.getElementById("txtName").value=="")
{alert("NameNotFound");document.getElementById("txtname").focus();returnfalse;
}if(document.getElementById("txtemail").value==""){alert("EmailCantNotFind");document.getElementById("txtEmail").focus();returnfalse;}varemailPat="^[a-zA-Z0-9_.]+@[a-zA-Z0-9-]+[.a-zA-Z]+$";varemailID=document.getElementById("txtEmail").value;varmatchArray=emailID.match(emailPat);if(matchArray==null){alert('Youremailaddressseemsincorrect.Pleasetryagain.');document.getElementById("txtEmail").focus();returnfalse;}vardigits="0123456789";vartemp;for(i=0;document.getElementById("txtZip").value.length;i++){temp=document.getElementById("txtZip").value.substring(i,i+1);if(digits.indexOf(temp)==-1){alert("pleaseentercurrentzipcode");document.getElementById("txtZip").focus();returnfalse;}}returntrue;
}</script>第二步 就是 .cs中的 Page_load 事件 添加如下代码:
protectedvoidPage_Load(objectsender,EventArgse){btnSubmit.Attributes.Add("onclick","returnvalidate()");}本文地址：http://www.45fan.com/a/question/70461.html
