如何在select2 jquery中标记中设置默认值 [英] How to set Default Value in tagging in select2 jquery

问题描述

我正在将select2( http://ivaynberg.github.io/select2/)用于我的标记输入.在使用select2标记的示例中，代码看起来像这样.

I am using select2 (http://ivaynberg.github.io/select2/) for my tagging input. from the example in using select2 tagging the code is look like this.

 $("#e12").select2({tags:["red", "green", "blue"]});

现在我的问题是，如何像在 http:/中的页面示例中那样在输入中插入默认值. /Tagyn支持中的/ivaynberg.github.io/select2/，输入的默认值为'brown'，'red'和& 绿色".

now my problem is how can I insert default value in my input just like in the page example in http://ivaynberg.github.io/select2/ at Tagging Support, the input has a default value of 'brown', 'red', & 'green'.

推荐答案

您可以通过提供隐藏输入的值来初始化Select2控件:

You can initialize the Select2 control by providing a value for the hidden input:

<input type="hidden" id="e12" value="brown,red,green" />

然后您可以通过将数组传递给'val'方法来设置Select2控件的值:

And you can set the value of the Select2 control by passing an array to the 'val' method:

$('#tagSelect').select2('val', ['brown','red','green']);
