调整浏览器大小时使用jQuery更改图像src

问题描述

我有两个不同尺寸的图像，一个是用于小于759px的屏幕，另一个是用于大于759px的屏幕.

I have two different sized images, one if for screens smaller than 759px, the other is for screens larger than 759px.

我设法获取了图像的来源，以便在文档加载时根据窗口宽度进行更改.但是我真的很希望能够在调整浏览器大小的同时执行此操作，但是对于我一生来说，我无法做到这一点，它似乎仅在最初加载页面时有效.

I have managed to get the source of the images to change when the document loads depending on the window width. But I really would like to be able to do this when the browser is resized as well but for the life of me I can't get it to do that, it only seems to work when the page is initially loaded.

这是我的代码:

$(document).ready(function() {
    function imageresize() {
        var contentwidth = $(window).width();
        if ((contentwidth) < '700'){
            $('.fluidimage').each(function(){
                var thisImg = $(this);
                var newSrc = thisImg.attr('src').replace('x2', 'x1');
                thisImg.attr('src', newSrc);
            });
        } else {
            $('.fluidimage').each(function(){
                var thisImg = $(this);
                var newSrc = thisImg.attr('src').replace('x1', 'x2');
                thisImg.attr('src', newSrc);
            });
        }
    }

    imageresize();//Triggers when document first loads

    $(window).bind("resize", function(){//Adjusts image when browser resized
        imageresize();
    });
 });

推荐答案

首先尝试一下...

更改您的代码行

$(window).bind("resize", function(){//Adjusts image when browser resized
        imageresize();
    });

到

// Bind event listener
    $(window).resize(imageresize);

并将警报放在imageresize中以查看其是否有效...

and put alert inside imageresize to see if it works or not...

如果上述方法无法解决...我认为可能存在一个问题.

In case above do not work out...I believe there is one problem probably..

您的代码中有

$(document).ready(function() {

 $(window).bind("resize", function(){//Adjusts image when browser resized
        imageresize();
    });
}

因此，驻留在jquery中的函数可能无法正常工作.最重要的是，尝试使用简单的javascript；我有类似的问题，并使用普通的javascript解决了，jQuery在某些浏览器中无法正常工作.

So the function for reside inside jquery which may not work well. On top of that try using simple javascript; i had similar problem and solved using plain javascript and jquery did not work in some browsers.

声音听起来很奇怪，足以阻止您尝试，但可以正常工作...

Sound strange enough to stop you try at it but would work...
