附加选项以使用 jQuery 进行选择不起作用 [英] Appending options to select using jQuery doesn't work

问题描述

所以，我正在尝试使用 jquery 将选项附加到 HTML5 选择，但由于某种原因它不起作用.以下是我的代码:

 for (var i = 0; i 

这里的 itemsList 是一个项目数组，我想将其值附加到 id 也是 itemsList 的选择下拉框中.这是html代码:

<label for="itmesList">选择项目:</label><select id="itmesList"></select><div id="信息"></div>

知道我在这里做错了什么吗?谢谢！

解决方案

HTML:

<label for="itmesList">选择项目:</label><select id="selectItem"></select><div id="信息"></div>

JQuery:

var itemsList = ['a', 'b', 'c'];var 选项 = "";for (var i = 0; i < itemsList.length; i++) {警报(itemsList.length)；options += '<option value="' + itemsList[i] + '">'+ itemsList[i] + '';}$('#selectItem').html(options);

So, I am trying to append the options to the HTML5 select using jquery but it doesnt work for some reason. Following is my code:

    for (var i = 0; i < itemsList.length; i++) {
        WL.Logger.debug(itemsList[i]);
        var elem = $("<option/>").val(itmesList[i]).text(itemsList[i]);     
        $('#itemsList').append(elem);
    }

Here itemsList is an array of items whose value i want to append to the select dropdown box whose id is itemsList as well. here is the html code:

<div id="wrapper">
<label for="itmesList">Select item: </label>
<select id="itmesList"></select>
<div id="info"></div>
</div>

Any ideas what I am doing wrong here? Thanks!

解决方案

HTML:

<div id="wrapper">
<label for="itmesList">Select item: </label>
<select id="selectItem"></select>
<div id="info"></div>
</div>

JQuery:

var itemsList = ['a', 'b', 'c'];
var options = "";
for (var i = 0; i < itemsList.length; i++) {
    alert(itemsList.length);

    options += '<option value= "' + itemsList[i] + '">' + itemsList[i] + '</option>';

}
$('#selectItem').html(options);
