禁用Chrome下载栏.. [英] Disable chrome download bar..

问题描述

有没有办法为您的网络应用程序禁用Chrome下载栏？或者以编程方式安装禁用下载栏的Chrome扩展程序的方法？



我尝试了什么：



得到了这个选项chrome.downloads.setShelfEnabled（布尔启用）但除了下载权限之外它还说downloads.shelf权限。

如何设置这些使用JavaScript的权限？

Is there a way to disable the chrome download bar for your web application? Or a way to programmatically install a chrome extension that disables download bar?

What I have tried:

got this option chrome.downloads.setShelfEnabled(boolean enabled) but it says "downloads.shelf" permission in addition to the "downloads" permission.
How to set these permissions using JavaScript ?

推荐答案

试试这个：

Try this:

<script type="text/javascript">
function CheckPlugin()
{
var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
function findPlugin(ext) {
var thisExt, findExt;
for (var n = 0; n < navigator.plugins.length; n++) {
//alert("n value"+ navigator.plugins.length);
for (var m = 0; m < navigator.plugins[n].length; m++) {
//alert("m length:"+navigator.plugins[n].length);
thisExt = navigator.plugins[n][m].description.toLowerCase();
// alert("this exten"+thisExt);
findExt = thisExt.substring(0, thisExt.indexOf(" "));
//alert("findexes"+findExt);
if (findExt == ext)
return (true);
}
}
return (false);
}

if (is_chrome ==true) {
//alert("chrome browser");
if (findPlugin("acrobat")) {
//alert("Adobe Acrobat pdf viewer");
return true;
}
else {

alert("please disable the chrome pdf viewer and enable the Adobe Acrobat PDF viewer \n Please follow the steps:\n 1.Open the new tab 'chrome://plugins/' type the Address. \n 2. Click the Enable link in 'Adobe Acrobat' field. \n 3. click the Disable link in 'Chrome PDF Viewer'. \n 4. Close the tab and you can open the PDf files in chrome browser.");
return false;
}
}
else {
//alert("not chrome");
}
}

</script>
