Question

我有一个包含CSS和Jquery的HTML文件。当我在chrome和Firefox上测试它时，它工作正常。但是当我在IE上测试它时，只有CSS部分工作，JavaScript中的click功能根本不起作用。

$(document).ready(function(){

    var prev;       
    $('svg polygon').click(function(){
        var current = this;
        this.classList.add('mouseclick');
        $('#suburb').val(current.id);


        if((typeof prev != 'undefined') && (current != prev)){
            prev.classList.remove("mouseclick");
        }


        prev=current;
    });

    $("#forwardbutton").click(function(){
        $("#ctlform").submit();
    });

});

svg polygon{
    fill:none;
    stroke: white;
    stroke-width:1px;    
}

svg polygon:hover{
    fill: rgba(255, 255, 0, 0.3);
}

svg polygon.mouseclick{
    fill: rgba(255, 0, 4, 0.3);      !important;
    stroke-width: 1px;
    stroke: rgb(255, 0, 4);
}

解决方案：
classList.add（）在IE中不兼容因此将其更改为.attr（“class”，“classname”）将解决问题。

Answer 1

我猜它是classList的用法，只有部分支持，从IE10开始。您的开发人员工具是什么 - ＆gt; IE中的脚本告诉你，它应该给你一个错误。

此外，为什么使用jquery AND native JS。我个人讨厌jquery，但使用它的一个重要原因是跨浏览器支持，你可以在jquery中使用类方法。

Answer 2

作为Shan suggested，您的问题是您使用classList;但是，jQuery cannot add a class to an SVG。您可以通过在class上设置<svg>属性来解决这个问题。

您可以通过运行下面的代码段来查看此操作。

＆＃13;

$(document).ready(function(){
	
	var prev;       
	$('svg polygon').click(function(){
		var current = this;
		$(this).attr("class", "mouseclick");
		$('#suburb').val(current.id);

		if((typeof prev != 'undefined') && (current != prev)){
			$(prev).attr("class", "");
		}
				   
		prev=current;
	});

	$("#forwardbutton").click(function(){
		document.getElementById("ctlform").submit();
	});

});

＆＃13;

svg polygon{
	fill:none;
	stroke: white;
	stroke-width:1px;    
}

svg polygon:hover{
	fill: rgba(255, 255, 0, 0.3);
}

svg polygon.mouseclick{
	fill: rgba(255, 0, 4, 0.3); !important;
	stroke-width: 1px;
	stroke: rgb(255, 0, 4);
}

Answer 3

你的FF和Chrome缓存中必须有一个缓存版本的jQuery，因为我没有看到你在页面的任何地方都包含jQuery。

添加到BODY标记下面的页面：

<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>

编辑：

我看到你现在加了它。我刚用加载的jQuery lib测试了你的代码片段，它在IE11中运行。

PS - 很酷的效果！

Answer 4

抱歉，我没有看到JQuery导入<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>。

注意JQuery 2. *不适用于IE 6/7/8

Jquery Javascript仅适用于chrome和firefox，但不适用于IE
