如何解决jQuery-下拉列表选择的选项值未传递给ajax查询参数Metronic模板
我试图将下拉选择的选项传递给AJAX查询参数，并且我在有效负载中得到 null 。
如果我console.log()选定的选项，我可以得到正确的值，但似乎无法将其传递给AJAX查询参数选项。
我的代码中可以穿什么？
这是这些下拉菜单的HTML代码部分：
<label class="col-form-label">{{ __('general.labels.marketcenter') }}</label>
<div class="col-xl-2 col-sm-2">
<select class="form-control" id="kt_market_center_dropdown">
<option value=""></option>
@foreach($market_center_dropdown as $market_center)
<option value="{{ $market_center->id }}">{{ $market_center->mc_name }}</option>
@endforeach
</select>
</div>
<label class="col-form-label">{{ __('general.labels.megaagent') }}</label>
<div class="col-xl-2 col-sm-2">
<select class="form-control" id="kt_mega_agent_dropdown">
<option value=""></option>
@foreach($mega_agent_dropdown as $mega_agent)
<option value="{{ $mega_agent->id }}">{{ $mega_agent->megaagent_name }}</option>
@endforeach
</select>
</div>
<label class="col-form-label">{{ __('general.labels.teams') }}</label>
<div class="col-xl-2 col-sm-2">
<select class="form-control" id="kt_team_dropdown">
<option value=""></option>
@foreach($teams_dropdown as $teams)
<option value="{{ $teams->id }}">{{ $teams->team_name }}</option>
@endforeach
</select>
</div>
这是我的JavaScript代码（console.log($("#kt_market_center_dropdown option:selected").val());代码从下拉列表中获取了正确的值，并且与ajax查询参数中的代码相同）
"use strict";

解决方法
由于这是 GET 请求，您可以更改
params: { query: {...} }
仅：
data: {...}
除非您设置processData = false。
