动态创建引导选择器

问题描述

我正在使用引导选择插件.我正在填充一个动态创建的选择，如下所示:

I'm using the bootstrap select plugin. I am populating a dynamically created select like so:

var select = $('<select/>', {
     'class':"selectpicker"
}).selectpicker();

for (var idx in data) {
    if (data.hasOwnProperty(idx)) {
        select.append('<option value=' + data[idx].id+ '>' + data[idx].Text+ '</option>');
    }
}

select.selectpicker('refresh');

数据很好并且创建了一个选择，它无法识别我试图创建的引导选择器.在同一页面上有一个我不能动态创建的选择，它运行良好.

The data is fine and a select is created, it is not recognizing the bootstrap selectpicker i am trying to create. I have a select on the same page that I do not create dynamically and it works fine.

<select class="selectpicker">
    <option>Mustard</option>
    <option>Ketchup</option>
    <option>Relish</option>
</select>

$('.selectpicker').selectpicker();

如何动态创建引导选择?谢谢.

How do I dynamically create a bootstrap select? Thanks.

推荐答案

在调用selectpicker()之前，需要将创建的<select />附加到DOM上，如下所示:

You need to append the <select /> you create to the DOM before calling selectpicker() on it, something like this:

var $select = $('<select/>', {
     'class':"selectpicker"
});
for (var idx in data) {
    $select.append('<option value=' + data[idx].id + '>' + data[idx].Text + '</option>');
}

$select.appendTo('#myElement').selectpicker('refresh');

请注意append()的使用以及hasOwnProperty的删除-您已经在遍历对象的属性，因此方法调用是多余的.

Note the use of append(), and also the removal of hasOwnProperty - you're already looping through the properties of the object so that method call is redundant.
