http://hollywoodlacewigs.netsmartz.us/ 我正在从事上述项目。用户上传图片表单“上传”按钮,然后“选择区域”,然后单击“混合”按钮。这会将裁剪区域显示到其他图像上。单击电子邮件链接将组成两个图像。
但在此之前,我想让用户在裁剪图像之前“旋转”、“放大/缩小”图像。
我正在使用 jcrop,jquery ui 可拖动
这是脚本:
$(document).ready(function() {
$('#UploadForm').change('submit', function(e) {
e.preventDefault();
$('#SubmitButton').attr('disabled', ''); // disable upload button
$('#left-pic').hide();
$('#output').show();
//show uploading message
$("#output").html('<img style="margin:45px 0px 0px 35px; " src="images/ajax-loader.gif" alt="Please Wait"/>');
$(this).ajaxSubmit({
target: '#output',
success: afterSuccess //call function after success
});
});
});
function afterSuccess(){
$('#UploadForm').resetForm(); // reset form
$('#SubmitButton').removeAttr('disabled'); //enable submit button
$('#cropbox').Jcrop({
aspectRatio: 1,
onSelect: updateCoords,
bgOpacity: 0.5,
bgColor: 'white',
addClass: 'jcrop-dark',
setSelect: [ 34, 50, 134, 155 ]
});
}
function updateCoords(c){
$('#x').val(c.x);
$('#y').val(c.y);
$('#w').val(c.w);
$('#h').val(c.h);
}
function checkCoords(){
if (parseInt($('#w').val())) return true;
alert('Please select a crop region then press submit.');
return false;
}
$(function() {
$('#draggable3').draggable({
containment: $('#draggable3').parent(),
cursor: "move", cursorAt: { top: 56, left: 56 },
drag: function(event, ui) {
// Show the current dragged position of image
var currentPos = $(this).position();
// $("#xpos").text("CURRENT: \nLeft: " + (currentPos.left-580) + "\nTop: " + (currentPos.top-82));
$('#x3').val(currentPos.left-580);
$('#y3').val(currentPos.top-82);
}
});
});
