怎样在js函数中将动态创建的select元素放入已有的表单中进行提交?
我用的是createelement创建的一个select,名字是operator,但是不知道怎样将他加入已有的一个from里面。程序大概是这样的,按下newsearch后,会自动出现一个新的select,用户选择好后,按下submit建,我能构将这两哥select的值一次提交到新的页面。但实际的运行结果是,我只能得到原来静态的那哥select的值。
下面是源码,多谢高手指教:
<html>
<script type= "text/javascript ">
function addNewSearch()
{
var NewOperator = document.createElement( " <select name= 'Operator ' "> </select> ");
NewOperator.length = 3;
NewOperator.options[0] = new Option( 'And ', 'and ');
NewOperator.options[1] = new Option( 'Or ', 'or ');
NewOperator.options[2] = new Option( 'Not ', 'not ');
document.body.insertBefore(NewOperator);
}
</script>
<form name= "Search " action= "FilterResult.php " method= "post ">
<select name= "SearchWhat " onchange = "setSearchField(); ">
<option value = "both "> Both Event and Task </option>
<option value = "event "> Event </option>
<option value = "task "> Task </option>
</select>
<input type= "submit " value= "submit " name = "btn_submit "/>
<input type = "button " name= "newsearch " value= "New Search " onClick= "addNewSearch() ">
</html>
------解决方案--------------------你新增的位置不对,要放在FORM里才行
<html>
<script type= "text/javascript ">
function addNewSearch()
{
var NewOperator = document.createElement( " <select name= 'Operator '> </select> ");
NewOperator.length = 3;
NewOperator.options[0] = new Option( 'And ', 'and ');
NewOperator.options[1] = new Option( 'Or ', 'or ');
NewOperator.options[2] = new Option( 'Not ', 'not ');
document.getElementById( "div1 ").insertBefore(NewOperator);
}
</script>
<form name= "Search " action= "FilterResult.php " method= "post ">
<select name= "SearchWhat " onchange = "se
