javascript - 更改为 Javascript 中的链接
问题描述
在过去的几天（一整天）中，我四处寻找并付出了诚实的努力，但我似乎无法正确处理，所以我把它放回去至少能够在方向盘上显示 CLICK HERE。例如，单击此处可以访问 peredy1.com 等。我尝试了所有我找不到的示例（a.href、a href=" " 等）
你可以看到我尝试过的一种方法。另外，请在给我-1之前告诉我原因。在这里寻求帮助时，我似乎无法理解我在问题中做错了什么。
我需要做的是，当轮子停止时，它会显示该获胜选择的可点击链接。我没有写这个，但我定制了它。任何帮助将不胜感激。
这是有问题的部分

解决方案
我为你找到了解决方案。您在写入变量时出错data：
var data = [
{"label":"2 Songs", "value":1, "question":"<a href="https://www.peredy1.com">CLICK HERE</a>"}, // padding
{"label":"1 Song", "value":1, "question":"CLICK HERE"}, //font-family
{"label":"2 Songs", "value":1, "question":"CLICK HERE"}, //color
{"label":"1 Song", "value":1, "question":"CLICK HERE"}, //font-weight
{"label":"1 Song", "value":1, "question":"CLICK HERE"}, //font-size
{"label":"1 Song", "value":1, "question":"CLICK HERE"}, //background-color
{"label":"3 Songs", "value":1, "question":"CLICK HERE"}, //nesting
{"label":"1 Song", "value":1, "question":"CLICK HERE"}, //bottom
{"label":"2 Songs", "value":1, "question":"CLICK HERE"}, //sans-serif
{"label":"1 Song", "value":1, "question":"CLICK HERE"} //period
];
在写作问题上应该"<a href='https://www.peredy1.com'>CLICK HERE</a>"不要在双引号内使用双引号，因为它会导致问题。您可以在引用二中使用引用一。
如果你想 html 不要使用：
//populate question
d3.select("#question h1")
.text(data[picked].question);
你应该使用
//populate question
d3.select("#question h1")
.html(data[picked].question);
