Javascript 导出div内容的脚本在Chrome中工作，但赢得了'；我不能在Firefox中工作

我有以下脚本将div内容导出为文本：

JAVASCRIPT

  <script type="text/javascript">

      // Wait for the page to load first
        window.onload = function() {

          //Get a reference to the link on the page
          // with an id of "mylink"
          var a = document.getElementById("exportxt");

          //Set code to run when the link is clicked
          // by assigning a function to "onclick"
          a.onclick = function() {

            // Your code here...


function downloadInnerHtml(filename, elId, mimeType) {
    var elHtml = document.getElementById(elId).innerHTML;
    var link = document.createElement('a');
    mimeType = mimeType || 'text/plain';
    link.setAttribute('download', filename);
    link.setAttribute('href', 'data:' + mimeType  +  ';charset=utf-8,' + encodeURIComponent(elHtml));
    link.click(); 
}
var fileName =  'meucanvas.txt'; // You can use the .txt extension if you want
downloadInnerHtml(fileName, 'editor','text/plain');
            //If you don't want the link to actually 
            // redirect the browser to another page,
            // "google.com" in our example here, then
            // return false at the end of this block.
            // Note that this also prevents event bubbling,
            // which is probably what we want here, but won't 
            // always be the case.
            return false;
          }
        }

</script>

//等待页面先加载
window.onload=函数（）{
//获取对页面上链接的引用
//id为“mylink”
var a=document.getElementById（“exportxt”）；
//设置单击链接时要运行的代码
//通过将函数分配给“onclick”
a、 onclick=function（）{
//你的代码在这里。。。
函数下载InnerHTML（文件名、elId、mimeType）{
var elHtml=document.getElementById（elId）.innerHTML；
var link=document.createElement（'a'）；
mimeType=mimeType | |“text/plain”；
link.setAttribute（'下载'，文件名）；
link.setAttribute（'href'，'data:'+mimeType+'；charset=utf-8'，+encodeURIComponent（elHtml））；
link.click（）；
}
var fileName='meucanvas.txt'；//如果需要，可以使用.txt扩展名
下载InnerHTML（文件名，'editor'，'text/plain'）；
//如果你不想链接到
//将浏览器重定向到其他页面，
//“google.com”在我们这里的例子中，那么
//在该块末尾返回false。
//请注意，这也可以防止事件冒泡，
//这可能是我们想要的，但不会
//总是这样。
返回false；
}
}

HTML

但是，它在Firefox中不起作用。在铬上工作。如何使其跨浏览器兼容

是onclick事件吗？
您的问题在
窗口中。加载firefox中未触发的
函数。尝试改用JQuery
$（document）.ready（）
和其他JQuery函数（用于单击等）。JQuery为您处理这些交叉浏览器的内容

选中此项：

问题不一定是
window.onload

您的问题是没有在页面上添加link元素，请尝试以下操作：

function downloadInnerHtml(filename, elId, mimeType) {
    var elHtml = document.getElementById(elId).innerHTML;
    var link = document.createElement('a');
    mimeType = mimeType || 'text/plain';
    link.setAttribute('download', filename);
    link.setAttribute('href', 'data:' + mimeType  +  ';charset=utf-8,' + encodeURIComponent(elHtml));
    link.style.cssText = "position: aboslute !important; left: -9999px; visibility: hidden;";//hide element
    link.innerHTML = "text";
    document.body.appendChild(link);
    link.click(); 
    setTimeout(function(){
        document.body.removeChild(link);//remove element
    }, 1);
}

// Wait for the page to load first
window.onload = function() {

  //Get a reference to the link on the page
  // with an id of "mylink"
  var a = document.getElementById("exportxt");

  //Set code to run when the link is clicked
  // by assigning a function to "onclick"
  a.onclick = function() {

    // Your code here...
    var fileName =  'meucanvas.txt'; // You can use the .txt extension if you want
    downloadInnerHtml(fileName, 'editor','text/plain');
    //If you don't want the link to actually 
    // redirect the browser to another page,
    // "google.com" in our example here, then
    // return false at the end of this block.
    // Note that this also prevents event bubbling,
    // which is probably what we want here, but won't 
    // always be the case.
    return false;
  }
}

提示：
在某些浏览器中，您可能会使用“下载不起作用”属性（可能是手机）
尝试
应用程序/octet流
，例如：

function downloadInnerHtml(filename, elId, mimeType) {
    var elHtml = document.getElementById(elId).innerHTML;
    var link = document.createElement('a');
    mimeType = mimeType || 'application/octet-stream';
    link.setAttribute('download', filename);
    link.setAttribute('href', 'data:' + mimeType  +  ';charset=utf-8,' + encodeURIComponent(elHtml));
    link.style.cssText = "position: aboslute !important; left: -9999px; visibility: hidden;";//hide element
    link.innerHTML = "text";
    document.body.appendChild(link);
    link.click(); 
    setTimeout(function(){
        document.body.removeChild(link);//remove element
    }, 1);
}
...
downloadInnerHtml('test.txt', 'editor');//force download

谢谢Guillerme Nasimento，它现在起作用了。巴西致以最良好的问候。
function downloadInnerHtml(filename, elId, mimeType) {
    var elHtml = document.getElementById(elId).innerHTML;
    var link = document.createElement('a');
    mimeType = mimeType || 'application/octet-stream';
    link.setAttribute('download', filename);
    link.setAttribute('href', 'data:' + mimeType  +  ';charset=utf-8,' + encodeURIComponent(elHtml));
    link.style.cssText = "position: aboslute !important; left: -9999px; visibility: hidden;";//hide element
    link.innerHTML = "text";
    document.body.appendChild(link);
    link.click(); 
    setTimeout(function(){
        document.body.removeChild(link);//remove element
    }, 1);
}
...
downloadInnerHtml('test.txt', 'editor');//force download
