当您单击页面上的标签时,我正在尝试显示一个灯箱。基本上,js 试图获取 href 并使用它来获取宽度。(在 js 和 jquery 方面不是最好的)所以任何帮助都会非常感激。
我得到的错误:
错误:语法错误,无法识别的表达式:#?w=500, a[name=?w=500] @ http://code.jquery.com/jquery-latest.js:4680
html
<a href="#?w=500" rel="diff" class="poplight">
<h1 class="blue">diff</h1>
</a>
<div id="diff" class="popup_block">
<p>text in light box</p>
</div>
查询:
<script type="text/javascript">
$(document).ready(function() {
//When you click on a link with class of poplight and the href starts with a #
$('a.poplight[href^=#]').click(function() {
var popID = $(this).attr('rel'); //Get Popup Name
var popURL = $(this).attr('href'); //Get Popup href to define size
window.alert('2 test in the popup function ');
//Pull Query & Variables from href URL
var query= popURL.split('?');
var dim= query[1].split('&');
var popWidth = dim[0].split('=')[1]; //Gets the first query string value
//Fade in the Popup and add close button
$('#' + popID).fadeIn().css({ 'width': Number( popWidth ) }).prepend('<a href="#" class="close" style="float:right;">Close</a>');
//Define margin for center alignment (vertical horizontal) - we add 80px to the height/width to accomodate for the padding and border width defined in the css
var popMargTop = ($('#' + popID).height() - 80) / 2;
var popMargLeft = ($('#' + popID).width()) / 2;
//Apply Margin to Popup
$('#' + popID).css({
'margin-top' : -popMargTop,
'margin-left' : -popMargLeft
});
//Fade in Background
$('body').append('<div id="fade"></div>'); //Add the fade layer to bottom of the body tag.
$('#fade').css({'filter' : 'alpha(opacity=90)'}).fadeIn(); //Fade in the fade layer - .css({'filter' : 'alpha(opacity=90)'}) is used to fix the IE Bug on fading transparencies
return false;
});
//Close Popups and Fade Layer
$('a.close, #fade').live('click', function() { //When clicking on the close or fade layer...
$('#fade , .popup_block').fadeOut(function() {
$('#fade, a.close').remove(); //fade them both out
});
return false;
});
});
</script>
