使用 Javastramps 取得元素标题
原标题:Getting elements title s with javascript

我试图用以下代码 检索元素标题

function highlight(elem) {
    var e = new Array();
    if (elem.style.border ==  2px solid blue ) {
        elem.style.border =   ;
    } else elem.style.border =  2px solid blue ;
    e.push(elem.title);
    var x = document.getElementById("test");
    x.innerHTML = e;
}

但它不起作用。 我也尝试过通过这个。 在函数中命名并展示它仍然行不通。 现在我只通过这个。

任何想法吗?

最佳回答

看着你张贴在评论中的代码:

<a title="<?php echo $url;?>" href="#">
    <img class="photo-img" src="<?php echo $thumb?>" border="2" alt="" width="40" onClick="highlight(this)" />
</a>

我可以看到您正在通过一个没有 Elem 标题的 < code> img 元素元素。 您实际上想要访问父元素标题, 因为您的 < code> img 没有标题, 但父元素的父元素( < code> a ) 有:

elem.parentNode.title
问题回答

使用 elem.getAttritte( 标题) 。 它是浏览器不可知性溶液 。
