Question

怎么调用用JS动态改变表单form里的action值属性的方法

<script type="text/javascript">
function tiao() {
var x_url =getArgs("id");
document.getElementById("form1").action="Dwzj_add.aspx?id="+x_url;
}
function getArgs(strParame) {
var args = new Object( );
var query = location.search.substring(1);

var pairs = query.split("&"); // Break at ampersand
for(var i = 0; i < pairs.length; i++) {
var pos = pairs[i].indexOf("=");
if (pos == -1) continue;
var argname = pairs[i].substring(0,pos);
var value = pairs[i].substring(pos+1);
value = decodeURIComponent(value);
args[argname] = value;
}
return args[strParame];
}

</script>
<form id="form1" method="post" onsubmit="tiao();" action="">我这样写了没有效果

Answer 1

<form id="form1" method="post" onsubmit="tiao();" action="">
这句里去掉tiao()后面的分号

Answer 2

function tiao() {
var x_url =getArgs("id");
document.getElementById("form1").action="Dwzj_add.aspx?id="+x_url;
document.getElementById("form1").submit();
return false;
}
