Call a function of Controller "One" inside Controller "Two" - IONIC1

app.controller('One', ['$scope', '$rootScope'
    function($scope) {
        $rootScope.$on("CallParentMethod", function(){
           $scope.parentmethod();
        });

        $scope.parentmethod = function() {
            // task
        }
    }
]);
app.controller('two', ['$scope', '$rootScope'
    function($scope) {
        $scope.childmethod = function() {
            $rootScope.$emit("CallParentMethod", {});
        }
    }
]);




While $rootScope.$emit is called, you can send any data as second parameter.

Solution for IONIC2+  will be up soon.

Log execution time of function/Ajax Call

Initialization of the variable to store all logs in controller

$rootScope.timeSlots = {};

//Function to create object with eventname , start time, end time using ID

$scope.logEvent = function(Eventid, EventName, isEnd){
    if(isEnd == false){
         $rootScope.timeSlots[Eventid] = {
            "name": EventName,
            "startDate":new Date().getTime()
         };
    } else {
        $rootScope.timeSlots[Eventid]["endDate"] = new Date().getTime();
    }
};
Log starting time 
$scope.logEvent("function1","Function1 start Time", false);

Change timeout for connection request in iOS

Code to change ajax request timeout for ios and also for hybrid(Cordova) apps.

Find NSURLRequest in your native code. Change the timeoutInterval value.

Error: Database location or iosDatabaseLocation value is now mandatory in openDatabase call

if you are using Cordova sqlite plugin you may have this issue while open local DB file.

// Works on android but not in iOS

                   

Error: Database location or iosDatabaseLocation value is now mandatory in openDatabase call

Use below to open DB:
window.sqlitePlugin.openDatabase({ name: "testDB.db", location: 2, createFromLocation: 1});

Solution:

if(isAndroid){
                    // Works on android but not in iOS

                    _sqlLiteDB = $cordovaSQLite.openDB({ name: "testDB.db", iosDatabaseLocation:'default'}); 

} else{
                    // Works on iOS 

                    _sqlLiteDB = window.sqlitePlugin.openDatabase({ name: "testDB.db", location: 2, createFromLocation: 1});

error JSON.stringify()ing argument: RangeError: Invalid Date

There is minor bug in contact plugin in cordova ionic. contact list is loaded with error due to the birthdate field in contact card. Its bad practice to keep minor error in execution of code, It may effect to different OS versions.

error JSON.stringify()ing argument: RangeError: Invalid Date

Cordova Plugin: cordova-plugin-contacts
Verison: 2.1.0 "Contacts"

Open convertUtils.js file  

File Path: plugins/cordova-plugin-contacts/www/convertUtils.js

Find function "toCordovaFormat" and remove below try-catch code.

 try {
         contact.birthday = new Date(parseFloat(value));
} catch (exception){
          console.log("Cordova Contact toCordovaFormat error: exception creating date.");
}

add below code instead of try-catch

if (value !== null) {

        try {

                contact.birthday = new Date(parseFloat(value));

               

                //we might get 'Invalid Date' which does not throw an error

                //and is an instance of Date.

                if (isNaN(contact.birthday.getTime())) {

                       contact.birthday = null;

               }

               

        } catch (exception){

                console.log("Cordova Contact toCordovaFormat error: exception creating date.");

        }

}

Check below screenshot for better understand.

iOS contact card does not have value for "displayName". "displayName" is used for the android devices. So For iOS device, use "name.formatted" instead of "displayName".

Cheers.... Keep Coding... :)

Easily Track Javascript File and line number which has error

When all else fails, the issue may be caused by errors in your JavaScript application. A helpful way to determine this is to use the window.onerror function to track down your errors.

Easily Track Javascript File and line number which has error

window.onerror = function (err, fileName, lineNumber) {

   // alert or console.log a message

   alert(fileName, 'Line:', lineNumber, 'Error:', e.message);

};

Parameter info: 

// err: error message

// fileName: which file error occurs in

// lineNumber: what line error occurs on

Woocommerce issue when products and categories has same base path

404 on Product detail page?

Ran into this issue where I needed a url structure such as/shop/<category> and /shop/<category>/<product>/.

/shop/<category>/ works fine but once you click a product you get a nice looking 404 page.

My settings:
Product category base - /shop
Product permalink base -> Custom Structure - /shop/%product_cat%

The Fix:

Set the ‘Product category base’ to shop and the custom product base to /shop/%product_cat%.
Then in your functions.php file add this little snippet:
