jQuery get height&宽度 [英] jQuery get height & width

问题描述

我做了 if 函数来检查宽度是否< 100px。由于某种原因，它隐藏一切。任何人都知道为什么？

I made an if function to check if the width is < 100px. For some reason it hides everything. Anyone know why?

$(document).ready(function() {
var pic = $(".pic");

// need to remove these in of case img-element has set width and height
$(".pic").each(function() {
    var $this = $(this);
    $this.removeAttr("width"); 
    $this.removeAttr("height");

    var pic_real_width = $this.width();
    var pic_real_height = $this.height();
    if(pic_real_width<100){
    $(this).css("display","none");
    }
    });

 });

推荐答案

尝试：

$(document).ready(function() {
    $(".pic").each(function() {
        var pic = $( this );
        pic.removeAttr("width"); 
        pic.removeAttr("height");

        var pic_real_width = pic.width();
        var pic_real_height = pic.height();
        alert(pic_real_width);
    });
});
