write/read a file?

[Elvin Chu]

I tried this, it didn't work. Another question how can I read a file with path.
code
function saveTheFile(filename, content) {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
fs.root.getFile(filename, { create: true }, function (fileEntry) {

Code: Select all

                 fileEntry.createWriter(function (fileWriter) { 

    fileWriter.onwriteend = function (e) { 

                     }; 

  fileWriter.onerror = function (e) { 
                         alert('Error occured: ' + e.toString() + "\n File couldn't saved"); 
                     }; 

                     var contentBlob = new Blob([content], { type: 'text/plain' }); 

                     fileWriter.write(contentBlob); 

                 }, handleError); 

             }, handleError); 
         } 
     ); 

}
saveTheFile(bg.txt,"aaaaa");
/code

I fixed using

code
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {

fs.root.getFile("GREN/background.css",{create: true}, function(DatFile){

DatFile.createWriter(function(DatContent) {

var blob = new Blob(["Lorem Ipsum"],{type: "text/plain"});

DatContent.write(blob);

Code: Select all

 }); 

});

Code: Select all

         } 
     ); 

/code

It's hard to say for sure without knowing your code context here.

Could you explain with more details what you are trying to implement in application, what builder version you are using and on what device platform?

I tested on my phone with android,5.0
