求助，我发现不了问题。总是跑不动。
- HTML code
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta http-equiv="Pragma" content="no-cache"><link href="tecom_style.css" rel="stylesheet" type="text/css"><title></title><base target="_self"><script language="javascript">var sys_language = '0';</script><script language="javascript" src="prompt.js"></script><script language="javascript" src="tecomWebUtil_1.js"></script><script language="javascript" src="tecomWebUtil_2.js"></script><script language="javascript"> var smpstartnumber =100 ; var smpendnumber =150 ;function btnSave(){ alert("111111"); var datacheck = true; if(document.UCDGroupForm.UCDGroupstartnumber.value == ) { alert("The start number couldn't be NULL!"); datacheck = false; } var start = parseInt(document.UCDGroupForm.UCDGroupstartnumber.value); var end = start + 500; alert(start); alert(end); var groupnum; for(var i = 0; i < 500; i++) { groupnum = eval("group" + i.toString()).value; if(groupnum < start || groupnum > end){ alert("The GroupNO. is beyond the valid range!"); datacheck = false; } } if(datacheck==true) { if(ValidateForm(UCDGroupForm) != true) return false; var loc = "UCDGroup.pbx?"; UCDGroupForm.submit(); }}</script></head>这是JS部分
下面是那个按钮
- HTML code
<input type="button" value="Save Settings" onClick="btnSave()">
如上所述，点击button无反应。
错误控制台提示btnSave is not defined.
[解决办法]
点击按钮前就有错误吧？
比如，下面这行代码就有问题：
- JScript code
if(document.UCDGroupForm.UCDGroupstartnumber.value == )
[解决办法]
if(document.UCDGroupForm.UCDGroupstartnumber.value ==null )
[解决办法]
[解决办法]
if(document.UCDGroupForm.UCDGroupstartnumber.value ==)
这句话不完整，分析这个函数错误，你调用就会提示不存在了。
