在jquery .after()函数内部添加for循环 [英] add for loop inside jquery .after() function

问题描述

我想在jquery .after()函数内部使用for循环添加<option>标记. 我有以下代码:

I want to add <option> tag using for loop inside jquery .after() function. I have the following code:

$("#myid").after("<!--more tags here-->"+
                  "<select class='form-control' name='dropdownmenu'>"+
                  "for (i=0; i < 4 ; i++){"+
                  "<option>i</option>}"+
                  "</select>"+
                  "<!--more tags here-->")

但这不起作用，我得到的只是1个<option>标记，其中的字母i

But that doesn't work, all I get is 1 <option> tag with the letter i inside

推荐答案

您不能在js中循环.您可以执行以下操作.您可以先创建选择块，然后再附加它.代码未经测试，希望您能理解.

you can not loop in js like that. you can something like following. You can create your select block first and then append it. code not tested, hopefully you get the idea.

var test = "<select class='form-control' name='dropdownmenu'>";

for (i=0; i < 4 ; i++){
    test += "<option>"+i+"</option>}";                  
}
test += "</select>";

$("#myid").after(test);  // note: use . for class or # for id

您仍然可以通过这种方式添加更多标签:

you can still add more tags this way:

$("#myid").after("<span>start</span>"+test+"<span>end</span>");
