I m developing Android application. I'm integrating the sqlite into my application https://github.com/brodyspark/PhoneGap-sqlitePlugin-Android The below error is coming
Uncaught TypeError: Object # has no method 'exec'
while using the following code
window.sqlitePlugin.openDatabase({name: "DB"});
I have a form partial as follows:
_internet_service_form.html.erb
<%= simple_form_for @internet_service, remote: true do |f| %>
<%= f.input :start_date %>
<%= f.button :submit %>
<% end %>
When I render it in the new action of the controller, it returns a 500 internal server with no further explanation.
When I render it in the edit action of the controller, it renders correctly.
If I replace the partial with a text block with no rails tags in it, it renders correctly, so I know it's not a routing error.
new.js.erb
$("#result-content").html("<%= escape_javascript(render(partial: 'new')) %>");
new.html.erb
<%= render partial: 'internet_service_form' %>
internet_service_controller.rb
def new
@internet_service = InternetService.new
end
def edit
@internet_service = InternetService.find(params[:id])
end
These actions are being performed through AJAX, and the most useful logs I'm getting out of the development log are:

您需要确保在打开数据库之前等待 Cordova 加载。
// Wait for Cordova to load
document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
var db = window.sqlitePlugin.openDatabase({name: "my.db"});
// ...
}

看到这个链接 js 文件在这里可用 数据库连接在那里
window.addEventListener("DOMContentLoaded", init);
function init() {
pageshow = document.createEvent("Event");
pageshow.initEvent("pageshow", true, true);
tap = document.createEvent("Event");
tap.initEvent("tap", true, true);
pages = document.querySelectorAll('[data-role="page"]');
numPages = pages.length;
links = document.querySelectorAll('[data-role="link"]');
numLinks = links.length;
//checkDB();
document.addEventListener("deviceready", checkDB, false);
}

function checkDB() {

在 Manifest.xml 中，您必须添加与 SQLite 相关的插件。然后它将起作用。
