篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Js下载文件到本地(兼容多浏览器)相关的知识,希望对你有一定的参考价值。
在客户端通过js下载文件,试过几种下载方式,iframe方式仅限于IE浏览器,window.open(url),location.href=url 这两种方式在chrome浏览器还会是直接打开文件而不是下载,百度N久没有结果,在谷歌还是找到答案了,下载链接在此。
window.downloadFile = function (sUrl) { //ios devices do not support downloading. We have to inform user about this. if (/(iP)/g.test(navigator.userAgent)) { alert(‘Your device does not support files downloading. Please try again in desktop browser.‘); return false; } //If in Chrome or Safari - download via virtual link click if (window.downloadFile.isChrome || window.downloadFile.isSafari) { //Creating new link node. var link = document.createElement(‘a‘); link.href = sUrl; if (link.download !== undefined) { //Set html5 download attribute. This will prevent file from opening if supported. var fileName = sUrl.substring(sUrl.lastIndexOf(‘/‘) + 1, sUrl.length); link.download = fileName; } //Dispatching click event. if (document.createEvent) { var e = document.createEvent(‘MouseEvents‘); e.initEvent(‘click‘, true, true); link.dispatchEvent(e); return true; } } // Force file download (whether supported by server). if (sUrl.indexOf(‘?‘) === -1) { sUrl += ‘?download‘; } window.open(sUrl, ‘_self‘); return true; } window.downloadFile.isChrome = navigator.userAgent.toLowerCase().indexOf(‘chrome‘) > -1; window.downloadFile.isSafari = navigator.userAgent.toLowerCase().indexOf(‘safari‘) > -1;
