我需要使用Phonegap创建一个iOS应用来保存HTML表单。但是，我对iOS或Phonegap并不过分熟悉。谁能指出我正确的方向？
这是我的HTML：

这是我的functions.js文件：
(function($){
/* On Page Ready */
$(document).ready(function(){});
/* On Page Load */
$(window).load(function(){
// Size differences
var mainH = $('#main').outerHeight();
var sheaH = $('#secondary-header').outerHeight();
$('#secondary').height(mainH + sheaH - 40).hide();
// Form Validation and Sumbit
var form = $('#signup-form');
form.validate({
debug: true,
rules: {
firstname: {
required: true
},
lastname: {
required: true
},
email: {
required: true,
email: true
}
},
messages: {
firstname: {
required: "Please enter your first name."
},
lastname: {
required: "Please enter your last name."
},
email: {
required: "Please enter your email."
}
},
submitHandler: function(form){
form.submit();
$('#main, #secondary-header').fadeOut(400);
$('#secondary').fadeIn(500);
setTimeout(function(){
window.location.reload(1);
}, 8000);
}
});
});
/* On Window Resize */
$(window).resize(function(){});
})(window.jQuery);
我正在使用jQuery表单验证，并在验证后隐藏表单并显示“谢谢”然后重新加载页面。现在，如何将表单数据保存到iOS文件系统？该应用程序需要离线使用并保存信息，这就是为什么我需要存储在iOS中的信息。
答案 0 :(得分：2)
所以我意识到我的一切都是错误的。我需要将表单数据发布到数据库。该数据库用于收集所有提交的表单数据。我相信每次提交表单数据时都会覆盖.txt文件的想法。所以，我创建了两个页面。一页填写并提交表格。一页用于查看所有表单条目以及导出和清除数据库。

这可能看起来很疯狂。但是，它适用于我想要完成的任务。获取表单数据，将其保存在本地，然后将信息导出到.csv文件中。希望这能让其他人对类似的问题有所了解。感谢大家的帮助!!

首先安装cordova文件插件。 http://docs.phonegap.com/en/edge/cordova_file_file.md.html
cordova plugin install org.apache.cordova.file
使用JQuery（#id）.val（）或document.getElementById（'id'）。值来从表单HTML中捕获文本。
创建写文件的功能如下：
我从表单
中捕获的数据var dataForm = $('#someId).val(); // All your text from the form.
require文件系统和创建文件的功能。
function createTxtFile(){
// Request File System
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem){
fileSystem.root.getFile("myTxt.txt", {create: true, exclusive: false},
function(fileEntry){
// Create File
fileEntry.createWriter(WriteText, fail);
}, fail);
},
fail
);
}
写文字的功能。
function WriteText(writer) {
writer.onwriteend = function(evt){ // Fired when end write.
console.log("End write text in file");
};
writer.write(dataForm);
}
