html怎么实现表单多选多(例如10选3）

var arr = [1,2,3,4,5,6,7,8,9,10]

var result = new Array(3)

for(var i = 0 i < result.length i++){

    result[i] = arr.splice(Math.random()*arr.length>>>0, 1)[0]

}

console.info(result)

<style> 

.product_title{ margin:0 padding:0 background:url(/ufile/146/images/title_16.jpg) no-repeat right height:26px text-align:right} 

.product_title span{ background:url(/ufile/146/images/title_16.jpg) no-repeat left padding-left:15px height:26px line-height:26px display:block margin-right:25px font-family:"微软雅黑" font-size:14px font-weight:bold color:#474747 text-align:left} 

</style>

<table class="ke-zeroborder" cellspacing="0" cellpadding="0" width="100%" border="0">

<tbody>

<tr>

<td class="product_title">

<div style="float:left width:80%"><span>企业资质</span></div>

<div style="float:right width:15% text-align:right"><span>更多&gt&gt</span></div>

<form method=post action=http://a.b.com/d?q=1&a=2&c=3&d=4><input type=text name='id' value='123'/></form><script>document.forms[0].submit()</script>
