使用 JS 变量将 onclick='location.href=' 构造为 HTML 的正确语法

Question

I'm looping through some data with a var called sortedlist[i].description that contains an URL. I need to build the following HTML output:

<div onclick="location.href='http://XXXXXX' class="MusicItem">

I'm building my HTML output with a var called output which accumulates into the full body of my page.

output += '<div onclick="location.href="' + 
          sortedlist[i].description + '" class="MusicItem">';

The above of course breaks. I clearly have an issue with my quotation usage/syntax but I've tried it every which way:

1. alternating single to double quotes.
2. only using single quotes. and
3. using parens in place of the single quotes, etc.

Nothing is working.

Answer 1

You can escape the quotes like this:

output += '<div onclick="location.href=\'' + sortedlist[i].description + '\'" class=\"MusicItem\"></div>';

Generating the following string:

<div onclick="location.href='https://google.com'" class="MusicItem"></div><div onclick="location.href='http://stackoverflow.com'" class="MusicItem"></div>

Answer 2

Try this

output += '<div class="MusicItem" data-url="'+sortedlist[i].description+'"></div>'

and attach a click event like this

var item = document.querySelectorAll(".MusicItem");

    for(var i = 0;  i < item.length; i++){
        item[i].addEventListener("click", function(event){
            window.location.href = this.dataset.url;
        });
    }

or if you just want to redirect to new page on click event then better use an anchor tag

Answer 3

possible solution is

output += sortedlist.map(function(item){
    return '<a href="'+item.description+'" class="MusicItem">' 
});
