downloader.js

function Downloader() {} 

Downloader.prototype.downloadFile = function(fileUrl, params, win, fail) { 

//Make params hash optional. 
if (!fail) win = params; 
PhoneGap.exec(win, fail, "Downloader", "downloadFile", [fileUrl, params]); 
}; 

PhoneGap.addConstructor(function() { 
PhoneGap.addPlugin("downloader", new Downloader()); 
PluginManager.addService("Downloader",  "com.phonegap.plugins.downloader.Downloader"); 
}); 

의 onclick = "다운로드()"

function download() { 
window.plugins.downloader.downloadFile("http://farm9.staticflickr.com/8010/7293758472_823d2eef5c_z.jpg", {overwrite: true}, 

     function(res) { 
     alert(JSON.stringify(result)); 
    }, function(error) { 
     alert(error); 
    } 
); } 

Answer 1

당신은이 같은 싶지 :

onclick="download(this.src)" 

function download(currentUrl) { 
window.plugins.downloader.downloadFile(currentUrl, {overwrite: true}, 

    function(res) { 
    alert(JSON.stringify(result)); 
}, function(error) { 
    alert(error); 
} 
); } 

Answer 2

CURRENTURL : 파일의 파일 이름/전체 경로를 당신은 서버에서 다운로드 중입니다

예 :

onclick="download(myfile.zip)" 

function download(fileName) { 
window.plugins.downloader.downloadFile(currentUrl, {overwrite: true}, 

function(res) { 
alert(JSON.stringify(result));}, 
function(error) { 
alert(error); 
} 
); }
