Jquery $（window）.height（）函数不返回实际的窗口高度 [英] Jquery $(window).height() function does not return actual window height
问题描述
我有一个页面，当用户滚动到底部时，我需要动态加载ajax内容。问题是JQuery没有返回正确的窗口高度。我之前使用过这个函数，从未见过它失败，但由于某种原因，它将返回与文档高度相同的值。我在这里有测试页面：bangstyle.com/test-images
I have a page that I need to dynamically load ajax content when the user scrolls to the bottom. The problem is that JQuery is not returning the correct window height. I have used this function before and have never seen it fail, but for some reason it will return the same value as the document height. I have the test page here: bangstyle.com/test-images
我已经将警报编码为在页面加载时显示，并且每当用户在顶部下方滚动500px时：
I have coded the alert to display at page load, and also whenever the user scrolls 500px below the top:
function scroller() {
if($(window).scrollTop() > 500){
delay(function(){ //200ms wait
pagecounter++;
sideshow();
alert("window height: " + $(window).height() + " scrolltop: " + $(window).scrollTop() + " document height: " + $(document).height());
return false;
}, 200 );
}
}
我之前试过发布这个但是我删除它，因为我没有得到解决方案。我希望可以发布我的测试页面的链接。顺便说一句，我已经在Mac Safari和Mac FF上测试了这个。我在其他页面上运行相同的代码，它工作正常。我觉得这个页面的dom必定会有一些东西导致JS失败，但不知道会是什么。
I tried posting this before but I deleted it as I didn't get a solution. I hope it is ok to post a link to my test page. BTW I have tested this on Mac Safari and Mac FF. I have run this same code on other pages and it works fine. I feel there must be something in the dom of this page that causes JS to fail, but no idea what that would be.
推荐答案
查看您的HTML源代码。
第一行应该是<！DOCTYPE html> 而你有< style> 标签代替。
Look at your HTML souce code.
The first line should be <!DOCTYPE html> and you have <style> tag instead.
因此，您的文档似乎在Quirks模式下运行，jQuery无法计算正确的窗口尺寸。
So it seems that your document is running in Quirks Mode and jQuery can't calculate correct window dimensions.
