Select2基本示例不起作用 [英] Select2 basic example not working
本文介绍了Select2基本示例不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使select2库与symfony2脚本一起使用.
I am trying to get select2 library working with symfony2 script.
我正在尝试实现提供的基本示例 https://select2.github.io/examples.html 页面.
I am trying to implement basic example provided https://select2.github.io/examples.html page.
因此，我已添加到页面标题:
Thus I added to my page header:
<!-- SELECT 2-->
<link href="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/css/select2.min.css" rel="stylesheet" />
<script src="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/js/select2.min.js"></script>
<!-- /SELECT2 -->
并遵循示例中提供的以下代码:
and following this code provided in example:
<script type="text/javascript">
$(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>
<select id="appbundle_items_accountdebet" name="appbundle_items[accountdebet]" class="js-example-basic-single"><option value="1">001 - Środki trwałe x</option><option value="2">001-001 - Środek trwały 1 </option><option value="3">001-002 - Środek trwały 2 </option><option value="4">002 - Kasa</option><option value="7">04-33 - test</option><option value="10">05 - dff</option></select>
不幸的是，由于没有视觉变化，我似乎做错了什么.
Unluckily it seems that I am doing something wrong as no visual changes takes place.
整个页面代码:

推荐答案
在完整的代码示例中，通过添加"来修复类选择器.在班级名称前，更改:
in your full code example, fix class selector by adding "." in front of class name, change:
<SCRIPT type="text/javascript">
$(document).ready(function() {
$("js-example-basic-single").select2();
});
</SCRIPT>
收件人:
<script type="text/javascript">
$(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>
-
在dom准备好代码之前，您是否在页面上包含了jquery?
have you included jquery on your page before dom ready code?
为我们提供JS控制台日志
provide us with JS console log
使用js调试器检查解析器是否到达:
check with js debugger if parser reaches:
$(.js-example-basic-single").select2();
$(".js-example-basic-single").select2();
您的代码至少在这里似乎可以正常工作: http://jsfiddle.net/8349tck1/
your code seems to work just fine at least here: http://jsfiddle.net/8349tck1/
