JadeJS Syntax

Fri, 15 Feb 2013 21:39:48 +0800

Indentation is VERY important.

No tabs allowed if you use spaces.

script(type=’text/javascript’, src=’/js/mobile.js’)

link(href=’/stylesheets/style.css’, rel=’stylesheet’)

meta(name=”viewport”, content=”width=device-width, initial-scale=1.0”)

div(data-role=”page”)

Javascript Object to JSON

Fri, 15 Feb 2013 21:37:23 +0800

// VARIABLES

var testList = [];

var newObj = new Object();

// INIT NEW OBJECT NAME

newObj.name = “Tom”;

// ADD NEW OBJECT TO ARRAY

testList.push(newObj);

// Make it a JSON first

var parsed = JSON.stringify(testList);

// Parse it

var temp = JSON.parse(parsed);

expressJS loading data first then rendering

Fri, 15 Feb 2013 21:34:40 +0800

app.use(function(req, res, next){

doWhatever …

req.object; // set variable so while rendering you can use it

next(); // to tell the server it’s ready to move on

});

Wed, 02 Jan 2013 11:51:00 +0800

Import this file

<script type=”text/javascript” src=”https://www.streetdirectory.com/js/map_api/m.php?api=0d95f0051bc63ad5a4905a95e8856a082e7a8f37”></script>

Add this to the html

<body onLoad=”initMap()”>

<div id=”map”></div>

And the jQuery Logic

//POSTAL CODE GRABBER

var geocode;

function initMap() {

geocode = new SDGeocode(map);

}

function set_data(json) {

if(json == null) return;

if(json.length == 0) return;

for (var i=0; i<json.length; i++) {

var rec = json[i];

$(‘.address’).html(“<center>” + rec.a + “</center>”);

$(“.error”).text(“”);

}

}

function search(region, keyword) {

gc = SDGeocode.SG;

var searchOption = {

“q”: keyword,

“limit”: 20

};

geocode.requestData(gc, searchOption , ‘0d95f0051bc63ad5a4905a95e8856a082e7a8f37’);

}

$(“#postal”).keyup(function(event) {

var length = $(this).val().length;

if(length == 6) {

var postal = $(‘#postal’).attr(‘value’);

search(‘SG’, postal);

}

});

Sun, 15 Jul 2012 14:41:00 +0800

# Create Browser

br = Watir::Browser.new :chrome

# Login To Facebook

br.goto ‘http://facebook.com’

# Fill in Forms

br.text_field(:name => ‘email’).set ‘username@email.com’

br.text_field(:name => ‘pass’).set ‘somepassword’

# Login

br.button(:value => ‘Log In’).click

# Go to Upload Page

br.goto ‘http://facebook.com/video/?upload’

# Add File To Upload Field

br.frame(:id => ‘upload_iframe’).file_field(:name => ‘file_baby’).set(filePath)

# Wait for ajax animation

sleep(3.0)

# Set File Title

br.text_field(:name => ‘title’).set fileName

# Save Info

br.button(:value => ‘Save Info’).click

filePath = pathList[i]

fileName = Pathname.new(filePath).basename

fileName = File.basename(fileName, ‘.*’)

print fileName

SQLITE3 Wrapper, FMDB

Thu, 22 Mar 2012 23:11:32 +0800

Source:

https://github.com/ccgus/fmdb

Implementation:

AppDelegate.h

@property (nonatomic, retain) NSString *databaseName;
@property (nonatomic, retain) NSString *databasePath;

AppDelegate.m (To check and create db if does not exist on device)

@synthesize databaseName, databasePath;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    self.databaseName = @”dbfile.db”;
    NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentDir = [documentPaths objectAtIndex:0];

    self.databasePath = [documentDir stringByAppendingPathComponent:self.databaseName];
    [self createAndCheckDatabase];

    return YES;
}

-(void) createAndCheckDatabase
{
    BOOL success;

    NSFileManager *fileManager = [NSFileManager defaultManager];
    success = [fileManager fileExistsAtPath:databasePath];

    if(success) return;

    NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:self.databaseName];

    [fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil];
}

Connecting to DB and retrieving data, remember to import the headers!

    NSString *databasePath = [(CAppDelegate *)[[UIApplication sharedApplication] delegate] databasePath];
    FMDatabase *db = [FMDatabase databaseWithPath: databasePath];

    [db open];

    FMResultSet *results = [db executeQuery:@”SELECT * FROM profile”];

    while([results next]) {
        Profile *p = [[Profile alloc] init];

        p.pID = (int) [results stringForColumn:@”id”];
        p.originalName = [results stringForColumn:@”originalName”];
        p.changedName = [results stringForColumn:@”changedName”];

        [profileList addObject:p];
    }

    [db close];

Displaying Results in UITableView

Thu, 22 Mar 2012 23:07:00 +0800

Can only use NSArray and not NSMutableArray.

If you have an NSMutableArray and want to display the data in it, just convert it to a NSArray using this.

profileArrayList = (NSArray *) profileMutableList;

@unlink($dir.’/’.$file);

}

closedir($handle);

}

Rearranging Cells in UITableView

Sun, 19 Feb 2012 17:13:27 +0800

Set allow moving of cells

- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}

The algorithm

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath {
    NSObject *o = [theDataObject.favouritesArray objectAtIndex:sourceIndexPath.row];

    if(destinationIndexPath.row > sourceIndexPath.row) //moving a row down
        for(int x = destinationIndexPath.row; x > sourceIndexPath.row; x—)
            [theDataObject.favouritesArray replaceObjectAtIndex:x-1 withObject:[theDataObject.favouritesArray objectAtIndex:x]];
    else //moving a row up
        for(int x = destinationIndexPath.row; x < sourceIndexPath.row; x++)
            [theDataObject.favouritesArray replaceObjectAtIndex:x+1 withObject:[theDataObject.favouritesArray objectAtIndex:x]];

    [theDataObject.favouritesArray replaceObjectAtIndex:destinationIndexPath.row withObject:o];

    [self.favouriteListTable reloadData];
