使用jQuery计算高度在Firefox和Chrome中不同 [英] Calculating height using jQuery differs in Firefox and Chrome

问题描述

我有一个问题，这里，但提供的解决方案不工作。问题是，我使用jQuery height（）函数返回一个div的高度。它在Firefox中工作得很好，但返回的值在Chrome中小于300px。

I have a question that was already asked here, but the solution offered there did not work. The problem is that I'm using the jQuery height() function to return the height of a div. It works nicely in Firefox, but returns a value that is 300px smaller in Chrome...

您可以看到此错误的示例在这里。虽然我必须说这是在希伯来语。虽然这不应该很重要...

You can see an example of this bug here. Though I must say it's in Hebrew. Though that shouldn't matter much...

有没有发生过这样的事？下面是计算高度的代码：

Has anyone had that happen before? Here's the code that calculates the height:

var heightLeftCol = $('#leftCol').height();
var sidebarHeight = $('#sidebar').height();
var minHeight = heightLeftCol > sidebarHeight ? heightLeftCol : sidebarHeight; 
$('#postArea').css('min-height', minHeight+100);

编辑：此问题不固定 / strong>在某种程度上我不喜欢，但它现在会做。这是我想出的解决方案：

This problem was not fixed but worked around in a way that I don't like, but it'll do for now. Here's the "solution" that I came up with:

if (jQuery.browser.safari) {
    $('#postArea').css('min-height', minHeight+400 + 'px');
}
else {
    $('#postArea').css('min-height', minHeight+100 + 'px');
}

由于Safari和Chrome都是在WebKit上运行的，所以 browser.safari 实际上选择了chrome。我绝对不认为这是一个最佳的解决方案。

Since both Safari and Chrome run on WebKit, the browser.safari actually selects chrome as well..I definitely do not consider this an optimal solution.

谢谢！

推荐答案

在Chrome中，div的高度不包括300像素高像sheli.jpg，因为它没有在html或css中的任何地方指定。如果您在< img>中指定 height =300标签或 height：300px; 作为其样式的一部分，它将工作。

In Chrome, the height of the div does not include the height of your 300-pixel tall image "sheli.jpg" because it isn't specified anywhere in the html or css. If you specify the height="300" in your <img> tag or height: 300px; as part its style, it will work.
