在ajax请求中创建的select标记不会显示在HTML文件中
在ajax请求中创建的select标记不会显示在HTML文件中
提问于 2019-06-24 07:37:38
我想通过ajax请求加载一些选项，并将它们显示在选择标记HTML中。在获取数据并手动创建select标记后，HTML文件没有显示select标记。我使用jquery并将代码放在其他文件中。我尝试将ajax请求放入$(Document)、.ready()和function中，但都不起作用。

}在chrom控制台中，result在这里：
<select id="addSiteSelectCenterInput" class="form-control select" style="display: none;">
<option value="5d0f86f0a2b7a41bdcd3c91f">sdf</option><option value="5d0f9c4067731820fcabf1eb">scaasdad</option></select>回答 1

根据您的控制台结果，<select>不可见，因为它具有style="display: none;"属性。
您提供的代码中没有添加该属性的内容，因此您显然没有给我们提供所有相关的代码。
所以你要么需要删除这个属性...或者从一开始就不要隐藏控件。
要通过jQuery显示，请使用.show()...
$("#addSiteSelectCenterInput").show()或者在vanilla JS中更改style.display属性...
document.getElementById("addSiteSelectCenterInput").style.display = "";页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
