前言：

协助项目需要实现一个签名的功能。

功能说明：1.有文本签名和头像签名。2.头像签名需要实现可拖拽功能。3.需要展示的是pdf的文件并需要获取签名位于pdf文件的相对位置。

功能一：实现拖拽

思路：H5拖拽及构造函数实现拖拽及缩放

要点：1.需要设置拖拽元素属性

　　　　draggable="true"　　

　　　2.可拖拽的元素设置ondragstart获取数据　　

　　 3.对可放置拖拽元素的设置ondragover函数

　　　　默认地，无法将数据/元素放置到其他元素中。如果需要设置允许放置，我们必须阻止对元素的默认处理方式。

　　 4.ondrop函数

　　设置放置后需要执行的方法。

 1  /*H5拖拽并复制*/
 2     var moveDemo=null;
 3     var _type;
 4     var divs=document.querySelectorAll(".left_list li");
 5     var showBox=document.querySelector(".section_main_pdf");
 6     for(var i=0;i<divs.length;i++){
 7         divs[i].ondragstart=function(e){
 8             moveDemo=this.querySelector("img");
 9             _type=this.querySelector(‘.list_name‘).innerText;
10         }
11     };
12     showBox.ondragover =function(e){
13         e.preventDefault();
14         //console.log(‘x:‘+ e.pageX+‘;y:‘+ e.pageY);
15     };
16     showBox.ondrop=function(e){
17         var _clone=moveDemo.cloneNode();
18         this.append(_clone);
19         console.log(_clone);
20         _clone.className=‘dragIcon‘;
21         $(_clone).css({
22             ‘width‘:‘100%‘,
23             ‘height‘:‘100%‘
24         }).attr(‘draggable‘,false);
25         $(_clone).wrap(‘<span class="img_outer"></span>‘);
26         if(_type==‘Signature‘){
27             $(_clone).parent().css({
28                 ‘position‘:‘absolute‘,
29                 ‘top‘: e.pageY,
30                 ‘left‘: e.pageX,
31                 ‘cursor‘:‘move‘,
32                 ‘display‘:‘inline-block‘,
33                 ‘border‘:‘2px solid‘
34             }).append(‘<span class="iconResize" style="position:absolute;display: inline-block;width: 10px;height: 10px;‘ +
35                 ‘cursor:se-resize;right:-5px;bottom:-5px;background-color:#fff;‘ +
36                 ‘border:2px solid;border-radius:50%"></span>‘).attr({
37                 ‘data-icon‘:‘signature‘,
38                 ‘data-page‘:config.defaultPage
39             });
40         }
41         else if(_type==‘PIN‘){
42             $(_clone).parent().css({
43                 ‘position‘:‘absolute‘,
44                 ‘top‘: e.pageY,
45                 ‘left‘: e.pageX,
46                 ‘cursor‘:‘move‘,
47                 ‘display‘:‘inline-block‘,
48                 ‘border‘:‘2px solid‘
49             }).attr({
50                 ‘data-icon‘:‘pin‘,
51                 ‘data-page‘:config.defaultPage
52             });
53         }
54     };

功能二：构造拖拽及缩放函数

思路：通过获取鼠标事件及元素位置

 1 /*构造拖拽及缩放函数*/
 2     $(document).mousemove(function(e) {
 3         if (!!this.move) {
 4             var posix = !document.move_target ? {‘x‘: 0, ‘y‘: 0} : document.move_target.posix,
 5                 callback = document.call_down || function() {
 6                         $(this.move_target).css({
 7                             ‘top‘: e.pageY - posix.y,
 8                             ‘left‘: e.pageX - posix.x
 9                         });
10                     };
11             callback.call(this, e, posix);
12         }
13     }).mouseup(function(e) {
14         if (!!this.move) {
15             var callback = document.call_up || function(){};
16             callback.call(this, e);
17             $.extend(this, {
18                 ‘move‘: false,
19                 ‘move_target‘: null,
20                 ‘call_down‘: false,
21                 ‘call_up‘: false
22             });
23         }
24     });

功能三：pdf展示

要点：引入pdf.js和pdf.worker.js进行API解析和核心解析

说明：1.pdf.js不能打开本地文件，需要服务器启动

　　 2.需要Firefox下运行报错才有提示(firefox的pdf解析)

 1 var loadingTask=PDFJS.getDocument(config.url);
 2         loadingTask.promise.then(
 3             function getPdf(pdf){
 4                 pdf.getPage(config.defaultPage).then(
 5                     function getPage(page){
 6                         var scale=1;
 7                         var viewport=page.getViewport(scale);
 8                         var canvas=document.getElementById(‘canvas‘);
 9                         var context=canvas.getContext(‘2d‘);
10                         canvas.height=config.outerHigh;
11                         canvas.width=config.outerWid;
12                         var renderContext={
13                             canvasContext:context,
14                             viewport:viewport
15                         };
16                         page.render(renderContext);
17                     },
18                     function pageError(msg){
19                         console.log(msg);
20                     }
21                 )
22             },
23             function pdfError(msg){
24                 alert(msg);
25             }
26         );

汇总：

1.签名js文件

  1 $(function(){
  2 
  3     /*H5拖拽并复制*/
  4     var moveDemo=null;
  5     var _type;
  6     var divs=document.querySelectorAll(".left_list li");
  7     var showBox=document.querySelector(".section_main_pdf");
  8     for(var i=0;i<divs.length;i++){
  9         divs[i].ondragstart=function(e){
 10             moveDemo=this.querySelector("img");
 11             _type=this.querySelector(‘.list_name‘).innerText;
 12         }
 13     };
 14     showBox.ondragover =function(e){
 15         e.preventDefault();
 16         //console.log(‘x:‘+ e.pageX+‘;y:‘+ e.pageY);
 17     };

 26         }).attr(‘draggable‘,false);
 27         $(_clone).wrap(‘<span class="img_outer"></span>‘);
