[英]Script that exports div content works in Chrome, but won't work in Firefox
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>
HTML
<div style="float:left; padding-left:5px;">
<a id="exportxt">
<label>
<button type="submit" value="#" style="border: 0; background: transparent">
<b>CLICK HERE DOWNLOAD AS TXT</b>
</button>
</label>
</a>
</div>
<div id="editor">
</br>
</br>
TEXT TEXT TEXT
但是,它不适用于Firefox。 适用于Chrome。 如何使其跨浏览器兼容?
这是onclick事件吗?
问题不一定是window.onload
。
您的问题是您没有在页面上添加链接元素,请尝试以下方法:
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;
}
}
在某些浏览器中,您可能会使用属性下载不起作用(可能是移动设备)尝试application/octet-stream
,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
你的问题是在window.load
函数中,它没有在firefox中触发。 尝试使用JQuery $(document).ready()
和其他JQuery函数(用于点击等)。 JQuery为你处理那些crossbrowser的东西。
