use*_*828 14 ajax jquery flask flask-wtforms bootstrap-select
我找到了flask-jquery-ajax示例,其中用户从车辆"Make"下拉菜单中选择项目,通过对所选择的make的模型列表进行AJAX请求来填充车辆"Model"下拉菜单.
我试图通过bootstrap-select替换下拉菜单,只要我在第二个下拉菜单中包含class ="selectpicker form-control",它就会在选择第一个下拉列表之后再填充它.
这是HTML模板:

<body>
<h1>Select Vehicle</h1>
<form class="form-horizontal" action="/" method="POST" >
<div class="input-group">
<span class="input-group-addon">Make:</span>
{{ form.make(id="make_select", class="selectpicker form-control") }}
</div>
<div class="input-group">
<span class="input-group-addon">Model:</span>
{{ form.model(id="model_select", class="selectpicker form-control") }}
</div>
<button type="submit">Submit</button>
</form>
{% if chosen_make %}
<h2>You selected:</h2>
<ul>
<li>Make ID: {{ chosen_make }}</li>
<li>Model ID: {{ chosen_model }}</li>
</ul>
{% endif %}
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript" src="//netdna.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.6.2/js/bootstrap-select.min.js"></script>
<script>
$('.selectpicker').selectpicker();
</script>
<script src="/assets/vehicle.js"></script>
</body>
</html>
这是负责填充下拉菜单的JavaScript 代码:
$("#make_select").change(function() {
var make_id = $(this).find(":selected").val();
var request = $.ajax({
type: 'GET',
url: '/models/' + make_id + '/',
});
request.done(function(data){
var option_list = [["", "--- Select One ---"]].concat(data);
$("#model_select").empty();
for (var i = 0; i < option_list.length; i++) {
$("#model_select").append(
$("<option></option>").attr(
"value", option_list[i][0]).text(option_list[i][1])
);
}
});
});
为什么class ="selectpicker form-control"来自bootstrap-select导致第二个下拉菜单不再被填充？

完成AJAX后,您需要重新加载插件:
$('#model_select').selectpicker('refresh');
要么
success: function(data)
{
$("#model_select").html(data).selectpicker('refresh');
}
