Question

如果我想使用innerHTML向元素添加内容，那么正确的语法是什么。以下是我的非工作示例：

   openNewWindow: function(content) {
popupWin = window.open(content,
    'open_window',
    'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0')
},

for (var index in mv.exifImages) {
        ele.innerHTML += "<p onclick = openNewWindow(mv.exifImages[index]> image" + index + "</p>";
    }

Answer 1

我认为是。变量index具有局部范围

for (var index in mv.exifImages) {
        ele.innerHTML += "<p onclick = 'openNewWindow(\"" + mv.exifImages[index] + "\")'> image" + index + "</p>";
    }

Answer 2

使用appendChild：

var myelement = document.getElementById("myelement");
myelement.appendChild( document.createTextNode("Example text inside myelemen") );

这比覆盖innerHTML更好，因为它保留了onclick事件，例如：
Is it possible to append to innerHTML without destroying descendants' event listeners?

innerHTML不是你的问题，你的代码缺乏上下文。

    openNewWindow: function(content) {
        popupWin = window.open(content,
            'open_window',
            'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0');
        // call to window.open ended here
    },
    // judging by the definition of openNewWindow and the comma above,
    // we are inside an object definition!

    // you cannot embed a for loop inside an object definition!!!
    for (var index in mv.exifImages) {
        ele.innerHTML += "<p onclick = openNewWindow(mv.exifImages[index]> image" + index + "</p>";
    }

将你的for循环放在合理的地方，比如在函数内部，或实际向我们显示你得到的错误。
