Question

在一个项目中，我设法通过phonegap工作来编写文件：

$("#download").live("click", function(){
                            writeFile();
                            });

function writeFile(){

            $.get("http://www.bartdekimpe.be/anoire/index.php/admin/getGamesUserJson/34", function(result){
                  json = result;
                  removeHTMLTags();
                   window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
                  });

}


function removeHTMLTags(){
            if(json){
                var strInputCode = json;
                /* 
                 This line is optional, it replaces escaped brackets with real ones, 
                 i.e. < is replaced with < and > is replaced with >
                 */ 
                strInputCode = strInputCode.replace(/(&nbsp;)*/g,"");
                strInputCode = strInputCode.replace(/&(lt|gt);/g, function (strMatch, p1){
                                                    return (p1 == "lt")? "<" : ">";
                                                    });
               // strTagStrippedText = '"';
                strTagStrippedText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");
                strTagStrippedText = $.trim(strTagStrippedText); // overbodige spaties weghalen
                //strTagStrippedText += '"';
            }};

function gotFS(fileSystem) {
            fileSystem.root.getFile("readme.txt", {create: true}, gotFileEntry, fail); 
        }

        function gotFileEntry(fileEntry) {
            fileEntry.createWriter(gotFileWriter, fail);
        }

        function gotFileWriter(writer) {
            writer.onwrite = function(evt) {
                console.log("write success");
            };
            writer.write(strTagStrippedText);


            readFile();
            // contents of file now 'some sample text'
           // writer.truncate(11);
            // contents of file now 'some sample'
           // writer.seek(4);
            // contents of file still 'some sample' but file pointer is after the 'e' in 'some'
            //writer.write(" different text");
            // contents of file now 'some different text'
        }
        // Einde FILE WRITER

        function fail(error) {
            console.log(error.code);
        }

在另一个项目中，我做了完全相同的事情，并且它不起作用，我创建了另一个项目，因为我需要重新开始。我是这样做的：

$(".startNew").live("click", function(){
                            writeFile();      
                            $.mobile.changePage($("#games"));
                            krijgSpellen();


                              });

function writeFile(){
            navigator.notification.alert("write file");
            $.get("http://www.bartdekimpe.be/anoire/index.php/admin/getGamesUserJson/34", function(result){
                  json = result;
                  removeHTMLTags();
                  window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
                  });


        }

        function removeHTMLTags(){
            if(json){
                var strInputCode = json;
                /* 
                 This line is optional, it replaces escaped brackets with real ones, 
                 i.e. < is replaced with < and > is replaced with >
                 */ 
                strInputCode = strInputCode.replace(/(&nbsp;)*/g,"");
                strInputCode = strInputCode.replace(/&(lt|gt);/g, function (strMatch, p1){
                                                    return (p1 == "lt")? "<" : ">";
                                                    });
                // strTagStrippedText = '"';
                strTagStrippedText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");
                strTagStrippedText = $.trim(strTagStrippedText); // overbodige spaties weghalen
                //strTagStrippedText += '"';
            }};


 function gotFS(fileSystem) {
            fileSystem.root.getFile("readme.txt", {create: true}, gotFileEntry, fail); 
        }

        function gotFileEntry(fileEntry) {
            fileEntry.createWriter(gotFileWriter, fail);
        }

        function gotFileWriter(writer) {
            writer.onwrite = function(evt) {
                console.log("write success");
            };
            writer.write(strTagStrippedText);


            readFile();
            // contents of file now 'some sample text'
            // writer.truncate(11);
            // contents of file now 'some sample'
            // writer.seek(4);
            // contents of file still 'some sample' but file pointer is after the 'e' in 'some'
            //writer.write(" different text");
            // contents of file now 'some different text'
        }
        // Einde FILE WRITER

        function fail(error) {
            console.log(error.code);
        }

当我这样做时，它不会写文件，真的很奇怪：

$(".startNew").live("click", function(){
                            writeFile();      
                            $.mobile.changePage($("#games"));
                            krijgSpellen();


                              });

它不会写文件，但是当我这样做时：

$(".startNew").live("click", function(){
                            writeFile();      
                              });

它确实有效，它会写一个文件

从您上面的评论中看来，您似乎是动态生成了与.startNew类的链接，这就是为什么它适用于live，如果您使用的是 jquery 1.7 + 使用on或使用delegate，因为直播是deprecated

$(function(){
 $(document).on("click",".startNew", function(){ writeFile(); });
});

或与代表

$(function(){
     $(document).delegate(".startNew","click", function(){ writeFile(); });
    });

在一个项目中我可以写一个文件但在另一个项目中我不能，真的很奇怪
