JCrop,如何清除所有的div宽度/高度标记? [英] JCrop, how to clear all the div width/height markup?
问题描述
我有一个配置文件图片系统,允许使用jCrop剪裁图片。我注意到,如果用户经历了几次过程,裁剪尺寸就不能正确计算,因为之前的图像仍然存在。我已经尝试了API的destroy()方法,但是它并没有从 .jcrop-holder
div及其子图像元素中清除图像源。
我怎样才能轻易摆脱这种情况?感谢。
我有一个老版本的jCrop类似的问题,并创建了一个自定义销毁函数。下面是它的要点:$ b
$ b pre $ $ $ $ $ $ $ $ $
$复位缩略图的坐标预览容器
$('#crop_preview')。data(coords.x,0);
$('#crop_preview')。data(coords.y,0);
$('#crop_preview')。data(coords.w,0);
$('#crop_preview')。data(coords.h,0);
//重置jcrop的src img和页面特定的全尺寸和预览divs的副本绑定
$(#crop,#crop_preview,.jcrop-holder img)。attr( src,);
函数crop_start()
{
//使用加载事件回调
'('#crop')初始化并删除先前的jCrop容器。 Jcrop({
onChange:showPreview,
onSelect:showPreview,
onLoad:hidePreview,
aspectRatio:1,
setSelect:[0,0,50,50] ,
minSize:[50,50],
allowResize:false,
allowMove:true
},function(){$(。jcrop-holder)。not :最后一个。)删除();});
//在不支持回调的情况下使用定时器删除以前的jCrop容器
/ *
window.setTimeout(function noblank(){
$( .jcrop-holder)。not(:last)。remove();
},1000);
* /
}
I have a profile picture system which allows image cropping using jCrop. I've noticed if the user goes through the process a few times, the crop dimensions are not calculated properly simply because the previous image is still there. I've tried the destroy() method from the API , but that doesn't clear the image source from the .jcrop-holder
div and its child image element.
How can I get rid of this easily? Thanks.
I had a similar issue with an old version of jCrop and created a custom destroy function. Here is the gist of it:
function crop_reset()
{
//Reset coordinates of thumbnail preview container
$('#crop_preview').data("coords.x", 0);
$('#crop_preview').data("coords.y", 0);
$('#crop_preview').data("coords.w", 0);
$('#crop_preview').data("coords.h", 0);
//Reset src of jcrop img and copies bound to page specific full size and preview divs
$("#crop, #crop_preview, .jcrop-holder img").attr("src", "");
}
function crop_start()
{
//Initialize and remove previous jCrop containers using load event callback
$('#crop').Jcrop({
onChange: showPreview,
onSelect: showPreview,
onLoad: hidePreview,
aspectRatio: 1,
setSelect: [0, 0, 50, 50],
minSize: [50, 50],
allowResize: false,
allowMove: true
},function(){$(".jcrop-holder").not(":last").remove();});
//Remove previous jCrop containers using timer if callback is not supported
/*
window.setTimeout(function noblank(){
$(".jcrop-holder").not(":last").remove();
}, 1000);
*/
}
