Question:

I am trying to write atleast 10 lines to a file using loops to append multiple lines in a file using PhoneGap, but everytime I run this code below, only able to add 1 line to a file as a newline. But 10 lines are not being printed in 10 iteration. Please suggest me how to rectify my problem using phoneGap javascript.

function gotFileWriter(writer) { for (var z = 0; z<= 10; z++) { console.log("normal write success"); writer.onwrite = function(evt) { console.log("write success"); }; writer.onwriteend = function(evt) { console.log("write end"); } writer.seek(writer.length); writer.write("id,updated,created,fname,lname,company,tags,type,label,value,source,sourceid\r\n"); writer.abort(); // I tried even commenting } }

Have you try this ?

function gotFileWriter(writer) { console.log("normal write success"); writer.onwrite = function(evt) { console.log("write success"); }; writer.onwriteend = function(evt) { console.log("write end"); } for (var z = 0; z< 10; z++) { writer.seek(writer.length); writer.write("id,updated,created,fname,lname,company,tags,type,label,value,source,sourceid\r\n"); writer.abort(); // I tried even commenting } }

This did the trick for me

Build one big string:

function gotFileWriter(writer) { var bigString = ''; for (var i=0; i<numberOfLines; i++) { bigString += line[i]; bigString += '\r\n'; } ...

Then do a massive write to the file:

... writer.onwrite = function (evt) { ... }; writer.onwriteend = function (evt) { ... }; writer.seek(writer.length); writer.write (bigString); }

You can use this for appending the text to file instead of looping

function gotFileWriter(writer) { writer.seek(writer.length); writer.write(" - append- \n"); }
