怎样用js创建Form表单并提交

<script >

//js动态创建form 提交表单
function formSubmit(elementValue) {

    var turnForm = document.createElement("form");   
    //一定要加入到body中！！   
    document.body.appendChild(turnForm);
    turnForm.method = 'post';
 turnForm.action = '/product/detail.htm';
 turnForm.target = '_blank';
 //创建隐藏表单
 var newElement = document.createElement("input");
    newElement.setAttribute("name","id");
    newElement.setAttribute("type","hidden");
    newElement.setAttribute("value",elementValue);
    turnForm.appendChild(newElement);
 
    turnForm.submit();
}

</script>

 

<a href="javascript:formSubmit('1')">点击我</a>
