我一直在尝试更好地掌握 jQuery,并且一直在想出一些随机页面来测试其中的一些。我制作了一个小型的模拟旅行社页面,其中包含一个带有出发地和目的地国家选项的表格。默认出发地/目的地是美国,美国的第二个选项出现在其下方。当用户选择美国以外的其他内容时,states 选项会消失,Chrome 除外。

脚本:(确实有 $(document).ready(function() ,不认为我需要发布整个 JS 文件)

 $('#destination').click(function(){
            // Show US States if Destination is US
            var destination = $('#destination').val();
            var domestic = 'USA';

            if (destination == domestic) {
                $('#usDest').css("display","inline");
            } else {
                $('#usDest').css("display","none");
            } 

html:

<div>
      <select name="destination" id="destination">
        <option value="USA" selected="selected">USA</option>
        <option value="Canada">Canada</option>

            <option value="Wyoming">Wyoming</option>
      </select> <!-- end usDest-->
      </div>

也许我遗漏了一些东西,但它适用于 Firefox、Safari 和 Internet Explorer 9 但不适用于 chrome 似乎很奇怪。

我也尝试过使用:

  $('#origin').click(function(){
            var origin = $('#origin').val();
            var domestic = 'USA';

            if (origin == domestic) {
                $('#usOrigin').removeClass("invisible");
                $('#usOrigin').addClass("visible");
            } else {
                $('#usOrigin').removeClass("visible");
                $('#usOrigin').addClass("invisible");
            }

与CSS:

.visible {
    display: inline;

}

.invisible {
    display: none;  
}

但这在 chrome 中也不起作用。(适用于其他浏览器)

任何建议,将不胜感激。

你可以很容易地使用jQueryhide()show()实现这个效果。但是根据人们在这里发布的内容,我猜你在JS 传播方面遇到了问题(代码中的错误)。这可能是由错误的扩展引起的,这就是您得到它的原因,而其他人没有。测试您的应用程序Incognito Mode以轻松暂时禁用扩展程序。在 Chrome 中启动隐身模式CTRL + SHIFT + N
