如果搜索内容是默认值的话就跳转到指定页面
<input type="text" name="ss" value="Sou"><input type="submit" name="bt" value="SouSuo">
点击提交时，如果输入框里是默认值的话就跳到指定的页面，否则正常提交，怎么写
[解决办法]
if(value=="Sou"){window.location=''}else{submit();}
[解决办法]
<form action="test.asp" onsubmit="return check(this)">
<input type="text" name="ss" value="Sou">
<input type="submit" name="bt" value="SouSuo">
</form>
<script type="text/javascript">
function check(f){
if( f.ss.value == f.ss.defaultValue ){
location.href = 'http://baidu.com/'
return false;
}
}
</script>
[解决办法]
<!DOCTYPE HTML><html> <head> <title> New Document </title> <meta charset="uft-8"> </head><script> function ceshi(e){ e = e || window.event; // 阻止submit的默认行为e.returnValue = false;if(e.preventDefault){ e.preventDefault();}var el=document.getElementById('Sou');if(el.value == "Sou"){window.location = 'http://www.baidu.com'}else{document.getElementById('frm').submit();}}</script> <body><form id="frm" action="http://g.cn"> <input style="text" id="Sou" name="ss" value="Sou"><input type="submit" value="SouSuo" onclick="ceshi()"></form> </body></html>
