Select2这个插件怎么给他默认值?我在他提交后收到的是数组,存储到数据库后,在此修改的时候要把之前提交的数组在作为默认值设置到插件上,可是我试了各种办法,如JSON,字符串,可这货就是不认。。输入选择框一直是空的,求设置方法,官方手册只有使用实例,demo非常简洁,没找到我要的部分。。。

直接在填入option的时候,加入selected属性就ok啦
<code> <select id="id_select" name="id_select" class="js-example-basic-multiple js-states form-control" multiple style="width: 460px"> <option value="1" selected>test1</option> <option value="2" selected>test2</option> <option value="3">test3</option> </select></code>
如果你是在js中填入option ,也可以的,但是要把插件的初始化函数select2()放在你填入option的步骤后面。
默认值也需要数组

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
