chrome height

复制代码 代码如下:





chrome下img加载对height()的影响











这是文字


这里显示结果。





将此代码在chrome运行,当alert窗口弹出时,将会发现页面的img并没有加载。

运行结果如下:

这是文字
showImg:112&0
showText:18

1、此处 img的默认宽度为112,但是我链接的img的宽度为1000,

2、此处img的高度为0,

现做如下改动
复制代码 代码如下:



运行结果为:

这是文字
showImg:1000&0
showText:18
img的高度仍旧为0

当为其设置高度之后,就可以正常获取到。

结论:在chrome下,img不设置宽高,通过jquery的width()和height()获取到的img的宽高将为112px * 0

求助:希望哪位大侠有好办法,能在不设置宽高情况下获取到正确的值。
