使用for循环获取表单元素中文
<script type="text/javascript">
function deal(form){
for(i=0; i < form.length; i++){
if(form.elements[i].value == ''){
alert(form.elements[i].title + "不能为空");
}
}
}
</script>
<form name="form1">
<tr>
<td>销售编号：</td>
<td><input type="text" name="num" title="销售编号"></td>
</tr>
<input type="button" onClick="deal(this.form);" id="change" value="提交">
<input type="reset" value="重置"/>
</form>
或者 我想提交以后获取输入的元素
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<form name="form1">
<tr>
<td>销售编号：</td>
<td><input type="text" name="num" title="销售编号" id="one"></td>
</tr>
<input type="button" onClick="deal();" id="change" value="提交">
<input type="reset" value="重置"/>
</form>
<script>
function deal(){
var one=document.getElementById("one").value;
alert(one);
}
</script>
</body>
</html>
