如何使用引导程序中的selectpicker插件在select上设置选定值 [英] How to set selected value on select using selectpicker plugin from bootstrap

问题描述

我正在使用 Bootstrap-Select 插件，如下所示:

I'm using the Bootstrap-Select plugin like this:

HTML :

<select name="selValue" class="selectpicker">
   <option value="1">Val 1</option>
   <option value="2">Val 2</option>
   <option value="3">Val 3</option>
   <option value="4">Val 4</option>
</select>

JavaScript :

$('select[name=selValue]').selectpicker();

现在，我想在单击按钮时将选择的值设置为此选择...类似这样的东西:

Now I want to set the value selected to this select when button clicked... something like this:

$('#mybutton').click(function(){
   $('select[name=selValue]').val(1);
});

但是什么也没发生.

我该如何实现?

推荐答案

该值已正确选择，但您没有看到它，因为该插件隐藏了真正的select并显示具有无序列表的按钮，因此，如果您希望用户在选择项上看到所选的值，您可以执行以下操作:

The value is correctly selected, but you didn't see it because the plugin hide the real select and show a button with an unordered list, so, if you want that the user see the selected value on the select you can do something like this:

//Get the text using the value of select
var text = $("select[name=selValue] option[value='1']").text();
//We need to show the text inside the span that the plugin show
$('.bootstrap-select .filter-option').text(text);
//Check the selected attribute for the real select
$('select[name=selValue]').val(1);

就像@blushrt指出的那样，更好的解决方案是:

Like @blushrt points out, a better solution is:

$('select[name=selValue]').val(1);
$('.selectpicker').selectpicker('refresh')

要选择多个值，请将这些值作为数组传递.

Edit 2:

To select multiple values, pass the values as an array.
