错误：未捕获的异常：[异常...“字符串包含...”

发布于 2025-01-08 09:39:16 字数 614 浏览 1 评论 0原文

我正在运行以下 javascript：

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "%");

        }
});

并且收到以下错误：

错误：未捕获的异常：[异常...“字符串包含无效的字符”代码：“5”nsresult：“0x80530005 (NS_ERROR_DOM_INVALID_CHARACTER_ERR)”位置： “http://code.jquery.com/jquery-1.6.4.min.js 行：2”]

我在尝试追踪这个问题时遇到了麻烦，因为它不能很好地描述问题或来源的问题。任何人都可以阐明这个问题吗？

谢谢

I am running the following javascript:

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "%");

        }
});

And I am getting the following error:

Error: uncaught exception: [Exception... "String contains an invalid
character" code: "5" nsresult: "0x80530005
(NS_ERROR_DOM_INVALID_CHARACTER_ERR)" location:
"http://code.jquery.com/jquery-1.6.4.min.js Line: 2"]

I'm having trouble actually trying to track this one down as it isn't very descriptive of the problem or the source of the problem. Can anyone shed some light on the problem?

Thanks

看来您不知道正确的语法。
试试这个：

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "px");

        }
});

It looks like you don't know the proper syntax.
Try this:

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "px");

        }
});

$(\'img\') 不起作用。应为 $('img')。还有其他一些地方您试图转义单引号，但您不需要这样做。您的代码应该看起来更像这样：

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "px");

        }
});

$(\'img\') won't work. Should be $('img'). There's a few other places where you are trying to escape the single quotes, but you don't need to. Your code should look more like this:

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "px");

        }
});

看起来它对我来说运行完美 - 尽管它没有改变图像的大小——所以问题可能出在代码/页面的其他地方。

然而，关于代码中的逻辑，我不确定您在这里想要做什么；

parseInt((W/666)*100)

您是否想让所有图片都达到最大宽度？即在浏览器中缩小图片的尺寸？如果是这样，为什么不将大小设置为固定值，例如；

$('img').each(
    function(){
        var maxwidth = 300;
        var w = parseInt(this.width);
        var h = parseInt(this.height)
        if(w > maxwidth){
            var hscale = parseInt(h/(w/maxwidth));
            $(this).width(maxwidth).height(hscale);
        }
});

Looks like it is running perfectly for me -- although it does not change the size the images -- so the problem is probably somewhere else in your code/page.

On the logic in the code, i am however unsure about what you are trying to do here;

parseInt((W/666)*100)

Are you trying to get all the pictures to be a width max size? i.e. downscaling the picture in the browser? If so, why not just set the size to a fixed value, like;

$('img').each(
    function(){
        var maxwidth = 300;
        var w = parseInt(this.width);
        var h = parseInt(this.height)
        if(w > maxwidth){
            var hscale = parseInt(h/(w/maxwidth));
            $(this).width(maxwidth).height(hscale);
        }
});
