我想獲得一個PHP變量通過JavaScript發送,我遇到了麻煩。我正在使用一個我在網上找到的jQuery彈出窗口,當用戶點擊一個項目時,我需要那個item_id變量可以在彈出窗口中獲取,我想添加一個窗體。從鏈接獲取JavaScript變量
我的PHP部分。
<a href="#?w=500&item_id='.$stock['id'].'" rel="popup1" class="poplight">
和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
//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
var itemID = dim[0].split('=')[2]; //Gets the second query string value
//Fade in the Popup and add close button
$('#' + popID).fadeIn().css({ 'width': Number(popWidth) }).prepend('<a href="#" class="close"><img src="/layout/close_pop.png" class="btn_close" title="Close Window" alt="Close" /></a>');
//Define margin for center alignment (vertical + horizontal) - we add 80 to the height/width to accomodate for the padding + border width defined in the css
var popMargTop = ($('#' + popID).height() + 80)/2;
var popMargLeft = ($('#' + popID).width() + 80)/2;
document.getElementById('popup1').innerHtml = itemID;
//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=80)'}).fadeIn(); //Fade in the fade layer
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;
});
});
我說什麼,我想你的工作,但它不會var itemID = dim[0].split('=')[2]; //Gets the second query string value
和document.getElementById('popup1').innerHtml = itemID;
究竟什麼是行不通的?你看過你的調試器嗎?難道,'#popup1'不存在嗎? – MCL 2013-02-17 18:58:45
