Question

我有一个简单的伙伴关系。表格净额:

<ul id="ctl00_ContentPlaceHolder1_BulletedList1">
    <li>No Lines Added</li>
</ul>

当用户开始填写表格的其他部分时,我想删除这一单一<代码><LI>,并开始用其他<代码><LI>内容充实清单。下面的法典是我是如何进行驱逐的:

function commitLine() {
    //if "No Lines Added" is the only item, remove all items, otherwise
    //continue with the additional item
    if ($("#ctl00_ContentPlaceHolder1_BulletedList1 li:nth-child(1)").text() == "No Lines Added") {
        $("#ctl00_ContentPlaceHolder1_BulletedList1 li").remove();
    }
    //code that begins the list population
}

如今,除IE8外,该法典在每一个浏览器中都发挥了巨大作用(假设是IE7, IE6。我一时就挨饿,可以 out。是否有人想到这个问题?

Answer 1

Is $("#ctl00_ContentPlaceHolder1_BulletedList1 li:nth-child(1)").text() returning text surrounded by whitespace in IE? If so, change that fragment to $.trim($("#ctl00_ContentPlaceHolder1_BulletedList1 li:nth-child(1)").text()) to remove it.

Answer 2

我认为,IE不支持孩子。

我添加了这两条法典,你的法典对:
