Set background color on div with jQuery?
提问by michaelmcgurk
I have been working with a piece of HTML / JavaScript code I found to produce a nice little hover effect: http://jsfiddle.net/RaEER/1/
我一直在使用一段 HTML/JavaScript 代码,我发现它产生了一个不错的悬停效果:http: //jsfiddle.net/RaEER/1/
You'll notice at first there is a white space above the placeholder image.
When I mouseover over it, it goes greenthen I mouseout, it goes light grey.
您首先会注意到占位符图像上方有一个空白区域。
当我鼠标悬停在它上面时,它变成绿色,然后我鼠标移开,它变成浅灰色。
Is there any way I can get this white area to be light grey when the page loads?
有什么办法可以在页面加载时让这个白色区域变成浅灰色?
If it helps, it's all to do with this line of code here:
如果有帮助,那就是这里的这行代码:
<div class="slides_item post-thumb" style="
background:#ededed!important"
onmouseover="
$(this).find('.hover_the_thumbs').css('background-color','rgba(0, 0, 0, 0.6)');
$(this).find('.magnify_this_thumb').css('left', '51%').css('opacity',1);
$(this).find('.hyperlink_this_thumb').css('left', '43%').css('opacity',1);
$(this).children('div').css('background','#8ec252');
$(this).find('.p_title a').css('color', 'white');
$(this).find('.p_exerpt p').css('color', 'white');
$(this).find('.p_title').css('border-top', '0');"
onmouseout="
$(this).find('.hover_the_thumbs').css('background-color','rgba(0, 0, 0, 0)');
$(this).find('.magnify_this_thumb').css('left', '-15%').css('opacity',0);
$(this).find('.hyperlink_this_thumb').css('left', '105%').css('opacity',0);
$(this).children('div').css('background','#fff');
$(this).find('.p_exerpt p').css('color', '');
$(this).find('.p_title a').css('color', '');
$(this).children('div').css('background','#ededed');
$(this).find('.p_title').css('border-top', '0');">

You can do it addding this in the Javascript or Js file:
您可以在 Javascript 或 Js 文件中添加此内容:
$(document).ready(function(){
$('.slides_item').children('div').css('background','#8ec252')
});

Anyway, you should separate the Javascript (jQuery in this case) from your HTML. You should o it including it in the header of the page, for example:
无论如何,您应该将 Javascript(在本例中为 jQuery)与您的 HTML 分开。您应该将它包含在页面的标题中,例如:
<script src="path_to_your_js/file.js"></script>

Ouch, why are you putting all javascript in the html code ?
哎呀,你为什么把所有的 javascript 都放在 html 代码中?
You should add some <script>
tags with your javacsript.
您应该<script>
在 javacsript 中添加一些标签。
To color on window load just add this :
要在窗口加载时着色,只需添加以下内容:
<script type="text/javascript">
$(window).load(function() {
$('.your-item-class').css('background-color','lightGrey');
});
</script>
