我已经找了很多,现在我真的不知道该怎么做。我的问题是我在HTML5文档中有一个选择控件,如下所示:
<label for="efectosId" >Elija un efecto</label>
<select id="efectosId" >
<option value="THRESHOLD" selected>Limite</option>
<option value="GRAY">Escala de grises</option>
<option value="OPAQUE">Opacidad</option>
<option value="INVERT">Invertir</option>
<option value="POSTERIZE">Posterizar</option>
<option value="DILATE">Desenfoque Dilatar</option>
<option value="BLUR">Desenfoque blur</option>
<option value="ERODE">Desenfoque Erosionar</option>
</select>
此外,在JavaScript文件中,我有以下代码:
$(document).ready(function(){
$("#efectosId").on("change",function(){
alert("hola mundo");
});
});
当我在单个文档中尝试加载jQuery库的代码时,它很顺利,但是当我需要在文档中使用它时,我按顺序加载jQuery库,jQuery移动库和jQuery ui库,然后它不起作用:
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
<script src="./bgrins-spectrum-98454b5/spectrum.js"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js" integrity="sha256-VazP97ZCwtekAsvgPBSUwPFKdrwD3unUfSGVYrahUqU=" crossorigin="anonymous"></script>
拜托,我可以得到任何支持吗?这让我很生气 谢谢!

我重新排序脚本标记并从jquery.min.js中删除了完整性
$(document).ready(function(){
$("#efectosId").on("change",function(){
alert("hola mundo");
});
});

似乎你在jquery之前加载bootstrap,改为使用这个命令:
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js" integrity="sha256-VazP97ZCwtekAsvgPBSUwPFKdrwD3unUfSGVYrahUqU=" crossorigin="anonymous"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
<script src="./bgrins-spectrum-98454b5/spectrum.js"></script>
来自bootstrap doc:
插件依赖
某些插件和CSS组件依赖于其他插件。如果你 单独包含插件,请务必检查这些插件 文档中的依赖项。 另请注意,所有插件都依赖于jQuery (这意味着必须在插件文件之前包含jQuery)。请教 我们的bower.json可以看到支持哪些版本的jQuery。

尝试加载jquery依赖浏览器,就好像你不需要jquery mobile,只是不加载它,我认为它们有冲突

好的,解决方案是当我使用jquery mobile,jquery ui和bootstrap库添加一个select时,select控件会改变我的HTML结构:
<div class="ui-selectmenu-menu ui-front ui-selectmenu-open" style="top: 105px; left: 769.5px;"><ul aria-hidden="false" aria-labelledby="efectosId-button" id="efectosId-menu" role="listbox" tabindex="0" class="ui-menu ui-corner-bottom ui-widget ui-widget-content" aria-activedescendant="ui-id-7" aria-disabled="false" style="width: 196px;"><li class="ui-menu-item"><div id="ui-id-2" tabindex="-1" role="option" class="ui-menu-item-wrapper">Limite</div></li><li class="ui-menu-item"><div id="ui-id-3" tabindex="-1" role="option" class="ui-menu-item-wrapper">Escala de grises</div></li><li class="ui-menu-item"><div id="ui-id-4" tabindex="-1" role="option" class="ui-menu-item-wrapper">Opacidad</div></li><li class="ui-menu-item"><div id="ui-id-5" tabindex="-1" role="option" class="ui-menu-item-wrapper">Invertir</div></li><li class="ui-menu-item"><div id="ui-id-6" tabindex="-1" role="option" class="ui-menu-item-wrapper">Posterizar</div></li><li class="ui-menu-item"><div id="ui-id-7" tabindex="-1" role="option" class="ui-menu-item-wrapper ui-state-active">Desenfoque Dilatar</div></li><li class="ui-menu-item"><div id="ui-id-8" tabindex="-1" role="option" class="ui-menu-item-wrapper">Desenfoque blur</div></li><li class="ui-menu-item"><div id="ui-id-9" tabindex="-1" role="option" class="ui-menu-item-wrapper">Desenfoque Erosionar</div></li></ul></div>
所以当我从jquery调用它时,我必须这样称呼它:
$("#efectosId-menu").on("click",function(e){
console.log(e.target.textContent);
});
