使用JS来给form 做提交

具体例子代码：

<SCRIPT language=javascript>

<!--

function go(formname)

{

var url = ;

formname.method = "get";

if (formname.myselectvalue.value == "1") {

document.search_form1.uhash.value = document.search_form1.uhash.value "";

}

formname.action = url;

return true;

}

//-->

</SCRIPT>

<form name="search_form1" onsubmit="return go(this)">

<input name="open" type="hidden" value="2" />
<input name="id" type="hidden" value="1778" />
<input name="uhash" onblur="if (value ==''){value='请输入关键字'}" onclick="if(this.value=='请输入关键字')this.value=''" onfocus="this.select()" onmouseover="this.focus()" size="30" value="请输入关键字" />
<input type="submit" value="搜索" />
</form>
