Question

我制造了这支笔，并且可以在我的路径图像上工作。

   //Circle

$(document).on('click','#Change_Green_Circle',function(e){
				e.preventDefault();
					 
  var img = document.getElementById('imgCircle');
  
   img.style.fill = 'Green';

});
    

$(document).on('click','#Change_Yellow_Circle',function(e){
				e.preventDefault();
					 
  var img = document.getElementById('imgCircle');
  
   img.style.fill = 'Yellow';

});

// Wiki

$(document).on('click','#Change_Green_wiki',function(e){
				e.preventDefault();
					 
  var img = document.getElementById('imgWiki');
  
   img.style.fill = 'Green';

});
    

$(document).on('click','#Change_Yellow_wiki',function(e){
				e.preventDefault();
					 
  var img = document.getElementById('imgWiki');
  
   img.style.fill = 'Yellow';

});


//Rest


$(document).on('click','#Rest',function(e){
				e.preventDefault();
					 
  var circle = document.getElementById('imgCircle');
  
   var wiki = document.getElementById('imgWiki');
  
    imgWiki.style.fill = 'Red';
    imgCircle.style.fill = 'Black';


});

但是

我想允许用户在我的网站上上传SVG，并执行我在上面的笔中所做的相同功能，所以我需要使用用户上传的图像的路径，怎么办？

1-我需要使用哪种编程语言？

2-如何走这条路    用户上传的SVg图像的数量

Answer 1

查看此小提琴：http://jsfiddle.net/recouwnh/19/

小提琴做什么：
01）按用户检索拖动的SVG图像的详细信息。
02）然后将图像数据转换为带有圆形，路径等适当标签的SVG标签。
03）单击“更改颜色”按钮时，脚本会通过查看SVG查找所有路径元素，并为它们提供随机颜色。

HTML代码：

<div class="viewer">
    <label class="viewer-switch">&nbsp;</label>
    <div class="alert-error"></div>
    <div class="introbox"></div>
    <div class="viewer-wrap"></div>
    <a style="display: none;"></a>
  <p>Drop your content here</p>
</div>
<div>
    <button type="button" name="btn_changecolor" id="btn_changecolor">Change Color</button>
</div>

JS代码：

var viewerCtrl = new ViewerController(document.querySelector('.viewer'));
// Cheap way to inform the user about errors.
var alertBoxTimeout, alertBox = document.querySelector('.alert-error');
window.onerror = function (msg) {
    alertBox.textContent = msg;
    alertBox.classList.add('show');
    if (!alertBoxTimeout) {
        setTimeout(function () {
            alertBox.classList.remove('show');
        }, 8000);
    }
};

$('#btn_changecolor').on('click', function(){
    var min=0, max=255, random1 = 0, random2 = 0, random3 = 0;
    $('.viewer-wrap svg path').each(function(){
        random1 = Math.random() * (+max - +min) + +min; 
        random2 = Math.random() * (+max - +min) + +min; 
        random3 = Math.random() * (+max - +min) + +min; 
        this.style.fill = 'rgb('+ random1 +', '+ random2 +', '+ random3 +')';
    });
});

02）在SVG动画上方创建的原始github链接：

03）https://maxwellito.github.io/vivus-instant/scripts/ViewerCtrl.js（用于创建可拖动区域并根据从用户上传图片中读取的数据准备SVG）

注意：仅使用SVG检查了此提琴的工作方式。要更改特定路径元素的颜色，您需要找出自己的方式。

希望这对您也有用。

用户在WebSite中上传的SVG图像的路径
