获取元素的价值

Question

我正在尝试检查一个元素的值,但它返回undefined虽然它在我检查它的类时有效.

HTML:

<div class='cube' value='test' onclick='checkCube(this)'></div>

JavaScript的:

function checkCube(cube) {      // - there's either one of those lines, not both)
    var check = cube.value;         //This is not working,
    var check = cube.className;     //This is.
    console.log(check);
}

Answer 1

valueproperty仅支持输入元素

使用getAttribute了非输入元素

var check = cube.getAttribute("value");
