jQuery 图像/悬停预览导致 IE7 中的行为不稳定

发布于 2024-08-19 16:08:28 字数 1854 浏览 7 评论 0原文

我在使用 jQuery 在 IE 中创建简单的缩放时似乎遇到了一些问题。 Firefox 一切正常,但大多数用户报告 IE 不稳定。

我已经禁用了 IE 中的代码(使用 jQuery.browser.msie),但如果可能的话,希望得到任何人的帮助。

我的jquery源代码如下(忽略upport函数)。

 this.imagePreview = function(){ 
 /* CONFIG */

  xOffset = 10;
  yOffset = 20;

  // these 2 variable determine popup's distance from the cursor
  // you might want to adjust to get the right result

 /* END CONFIG */
 $("a.preview").hover(function(e){
  this.t = this.title;
  this.title = "";
  this.inside = $(this).attr('inside')
  this.outside = $(this).attr('outside')
  var c = (this.t != "") ? "<br/>" + this.t : "";
  $("body").append("<p id='preview'><img width='260' src='"+ this.inside +"' />"+ c +"</p>");         
  $("#preview")
   .css("top",(e.pageY - xOffset) + "px")
   .css("left",(e.pageX + yOffset) + "px")
   .fadeIn("fast");      
    },
 function(){
  this.title = this.t; 
  $("#preview").remove();
    }); 
 $("a.preview").mousemove(function(e){
  $("#preview")
   .css("top",(e.pageY - xOffset) + "px")
   .css("left",(e.pageX + yOffset) + "px");
 });   
};
$(window).load(function(){imagePreview();});

以下是相关网页之一的示例: http://www.engreet .com/CategoryDe​​tail.aspx?cid=17。如果您滚动到源代码,您将看到缩略图具有内部的滚动/悬停预览,使用如下代码:

<a href="/CardDetailFull.aspx?cid=670" outside="http://static.engreet.com/ArtistFiles/51/Happy_Bela_Front_633998103802577482.jpg" inside="http://static.engreet.com/ArtistFiles/51/Happy_Bela_InsideRight_633998103832264982.jpg" title="Inside Preview" class="preview">
 <img src='http://static.engreet.com/ArtistFiles/51/_128X178_Happy_Bela_Front_633998103802577482.jpg' alt="" width="128" />
</a>

任何帮助将不胜感激。很高兴向某人发送一些免费卡片的代码!

谢谢, 亚当

I seem to be having some problems using jQuery to create a simple zoom in IE. In Firefox all is well, but IE is being reported as choppy by most users.

I've disabled the code in IE (using jQuery.browser.msie), but would love anyone's help if possible.

My jquery source code is below (ignore the upport function).

 this.imagePreview = function(){ 
 /* CONFIG */

  xOffset = 10;
  yOffset = 20;

  // these 2 variable determine popup's distance from the cursor
  // you might want to adjust to get the right result

 /* END CONFIG */
 $("a.preview").hover(function(e){
  this.t = this.title;
  this.title = "";
  this.inside = $(this).attr('inside')
  this.outside = $(this).attr('outside')
  var c = (this.t != "") ? "<br/>" + this.t : "";
  $("body").append("<p id='preview'><img width='260' src='"+ this.inside +"' />"+ c +"</p>");         
  $("#preview")
   .css("top",(e.pageY - xOffset) + "px")
   .css("left",(e.pageX + yOffset) + "px")
   .fadeIn("fast");      
    },
 function(){
  this.title = this.t; 
  $("#preview").remove();
    }); 
 $("a.preview").mousemove(function(e){
  $("#preview")
   .css("top",(e.pageY - xOffset) + "px")
   .css("left",(e.pageX + yOffset) + "px");
 });   
};
$(window).load(function(){imagePreview();});

Here is an example of one of the web pages in question: http://www.engreet.com/CategoryDetail.aspx?cid=17. If you scroll into the source, you'll see that the thumbnails have rollover/hover previews of the inside using code like such:

<a href="/CardDetailFull.aspx?cid=670" outside="http://static.engreet.com/ArtistFiles/51/Happy_Bela_Front_633998103802577482.jpg" inside="http://static.engreet.com/ArtistFiles/51/Happy_Bela_InsideRight_633998103832264982.jpg" title="Inside Preview" class="preview">
 <img src='http://static.engreet.com/ArtistFiles/51/_128X178_Happy_Bela_Front_633998103802577482.jpg' alt="" width="128" />
</a>

Any help would be GREATLY appreciate. Happy to send someone a code for a few free cards!

Thanks,
Adam

问题最终是透明背景 PNG 图像重复出现。它的尺寸为 1x1,填充了 755x600 的方形画布。通过将其增加到 25x25,所有问题都得到解决。令人疯狂的是,这个问题如何通过影响 jQuery 来表现出来,而最终是 IE 的疯狂渲染导致了这个问题!

希望这对将来的人有帮助。

The problem ended up being a transparent background PNG image that was being repeated. It was 1x1 and filling a 755x600 square canvas. By increasing this to 25x25, all issues resolved. It was crazy how this problem displayed itself by affecting jQuery when ultimately it was IE's crazy rendering that cause the problem all along!

Hope this helps someone in the future.
