js中对form表单进行input元素的添加与删除

js中对form表单进行input元素的添加与删除

1、添加input标签

createFormChildInput: function createFormChildInput(fm, id, name, value){
   var tmpInput=$("");
   tmpInput.attr("id", id);
   tmpInput.attr("name", name);
   tmpInput.attr("value", value);
   fm.append(tmpInput);
   fm.submit();
}

2、删除input标签

deleteFormChildInput: function deleteFormChildInput(inputId){
    //某个标签
    var inputId = document.getElementById(inputId);
    //删除
    inputId.parentNode.removeChild(inputId);
}

3、调用点

// 表单中新增两个标签selectPolicyInfo
var data.fm = $("#" + formId);
service.createFormChildInput(data.fm, 'selectPolicyInfo', 'selectPolicyInfo', page.params.selectPolicyInfo);
