验证客户输入

1.验证输入是否为手机号码或电话号码

 1 <script type="text/javascript">  
 2 String.prototype.Trim = function() {  
 3   var m = this.match(/^\s*(\S+(\s+\S+)*)\s*$/);  
 4   return (m == null) ? "" : m[1];  
 5 }
 6 
 7 String.prototype.isMobile = function() {  
 8   return (/^(?:13\d|15[89])-?\d{5}(\d{3}|\*{3})$/.test(this.Trim()));  
 9 } 
10 
11 String.prototype.isTel = function()
12 {
13     //"兼容格式: 国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(3位)"
14     //return (/^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(this.Trim()));
15     return (/^(([0\+]\d{2,3}-)?(0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/.test(this.Trim()));
16 }
17 
18 function chkForm() {  
19     with(document.form1){
20         if (tel.value.isMobile()||tel.value.isTel())  {  
21             tel.value = tel.value.Trim();  
22             alert("您的电话/手机号码是:" + tel.value);
23             return true;  
24         } 
25         else {  
26             alert("请输入正确的手机号码或电话号码\n\n例如:13916752109或0712-3614072"); 
27             tel.focus();
28             return false;        
29         }          
30     }
31 }  
32 </script>  
33 <form name="form1" method="post" action="" >  
34     <input type="text" name="tel" value="13916752109" size="15" />
35     <input type="button" value="测 试"  onclick="return chkForm()"/>  
36 </form>  
37 

2.验证只能输入数字

<SCRIPT LANGUAGE="JavaScript">

<!--

function limitNum(obj) {

    if(obj.value.replace(/[\d+]/ig,"").length>0) {

        alert('请输入数字')

    }

}

//-->

</SCRIPT>



<input name="textfield1" type="text" id="textfield1" style="width:60;" onKeyup="limitNum(this)" />
<!--<asp:textbox name="dealtime" type="text" size="25" id="dealtime" runat="server" Width="42px" MaxLength="5" onpropertychange="limitNum(this)"></asp:textbox>-->
