javascript - Get Imagesize in jQuery -

-

i want imagesize in jquery, have code. works point of 

alert (v);

i wonder wrong rest when v contains value.

 var v = $('#xxx input').val();     alert (v);     var newimg = new image();     newimg.src = v;     var height = newimg.height;     var width = newimg.width;     alert ('the image size '+width+'*'+height);

thanks jean

your code image size won't work. image loads asynchronously, height , width not available immediately. you'll need following:

var newimg = new image(); var height, width;  newimg.onload = function() {     height = newimg.height;     width = newimg.width;     window.alert('the image size '+width+'*'+height); };  newimg.src = v;

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
