angularjs, use a function in the routing as the templateUrl
It's possible to use a function as the templateUrl. The official documentation for $routeProvider states:
templateUrl – {string=|function()=}
$routeProvider official documentation
In javascript, a function has the syntax of:
function() {code here}
But the documentation shows:
function()=
Using function()=Code Here doesn't work. What is the syntax for using a function for the templateUrl in angularjs routing?
If I use something like:
when('/Store/:StoreId', {
templateUrl: function()=webPages/Stores.php?storeID=' + :StoreId,
controller: 'storeParseData'
This does not work. I guess that the URL match for :StoreId is automatically stored in $routeProvider . I've tried using $scope , $location , and $routeProvider in various different ways with no success. I'm looking for the simplest and most straight forward way to pass a URL # hash id to the templateUrl.
The reason I need to inject dynamic info into the templateUrl, is because the page I'm loading is a PHP file that runs PHP code when loaded. The PHP code retrieves info from the hash # URL. Retrieving the :StoreId in the controller won't help me. I want the PHP file to retrieve data from the server side rather than the front end JavaScript controller.
Here is the PHP code:
<?php
//There are two basic scenarios. 1) Get all Store names to populate the Store List
// 2) Get all the postings from a particular user, (store)
// If the URL has 'cat=something', then get all the store data
// If the URL does NOT have 'cat=something', then get the store data.
//Only get the store names if DIV with the store names is empty, otherwise
//just get the stores listings.
$storeNames = file_get_contents('https://NameOfDataURLHere.com/.json');
//information that was previously put into the URL string ending, is parsed with the following code.
$urlPiece = $_SERVER['REQUEST_URI'];
echo("url Piece: ".$urlPiece);
//find the position of the first character in the URL string with search criteria: 'storeID='.
//First the URL is checked for 'storeID='. If 'storeID=' exits in the URL, then the page routing injected 'storeID='
//as a string for an argument to be passed. If no argument was passed, then 'storeID=' string.
$posOfEqualSign = strrpos($urlPiece,"storeID=");
echo("<br>");
echo("posOfEqualSign: ".$posOfEqualSign);
echo("<br>");
//If the string 'storeID=' was found, it's okay to proceed.
if (isset($posOfEqualSign) && strlen($posOfEqualSign) > 0) {
//the substr function in PHP doesn't need an length designation if you want the default to go to the end of the string.
$storeID = substr($urlPiece,$posOfEqualSign + 8);
echo("storeID Length: ".strlen($storeID));
echo("<br>");
echo("storeID: " . $storeID);
echo("<br>");
}
if (isset($storeID) && strlen($storeID) > 3) {
//get all listings for the store out of the listings database with the store ID
//The store ID was retrieved from the URL. The store ID was put into the URL when the user clicked the store name.
$storeListings = file_get_contents('https://NameOfDataURLHere.com/'.$storeID.'/.json');
$listingsDecoded=json_decode($storeListings,true);
echo("storeListings: ".$storeListings);
echo("<br>");
if (strlen($storeListings) > 1) {
foreach ($listingsDecoded as $key => $value) {
//$keyValHere = """ . $key . """;
//echo "keyValHere " . $keyValHere;
echo"<br><br>";
echo "Level 1 Key: " . $key;
echo '<br><br>';
$storeListingsData = array();
foreach($value as $x=>$v) {
echo "Level 2 Key: " . $x;
echo"<br>";
echo "Lelvel 2 value: " . $v;
echo"<br>";
$specificListing = substr($v, 4);
$catToGetItemFrom = substr($v,0,3);
echo 'The Listing ID: ' . $specificListing;
echo"<br>";
echo 'The category: ' . $catToGetItemFrom;
if (strlen($catToGetItemFrom) > 0 && strlen($specificListing) > 1) {
if (ord($catToGetItemFrom) <= 109) { //ord returns the ASCII value of the first character of a string
$whatDB = "NameOfDBHere";
} else {
$whatDB = "NameOfSecondDBHere";
}
$oneStoreListing = file_get_contents('https://'.$whatDB.'.dataURL.com/'.$catToGetItemFrom.'/'.$specificListing.'/.json');
} else {
$oneStoreListing = "";
echo('one store Listing: '.$oneStoreListing);
}
if (strlen($oneStoreListing) > 1) {
//Keep adding single store listings to the array until the loop is done.
array_push($storeListingsData, $oneStoreListing);
}
}
}
}
echo '<br>';
echo('store Names: '.$storeNames);
echo('<br>');
echo('one store Listing: '.$storeListingsData);
}
?>
Data Injected Into A DIV with PHP for Later Retrieval:
<br>
<div id="idCatName" style="display: inline"><?php echo $catToGetItemFrom;?></div>
<br>
<div id="idStoreNames" style="display: inline"><?php echo($storeNames);?></div>
<br>
<div id="idStoreData" style="display: inline"><?php echo($storeListingsData);?></div>
The Solution - With a Little Help From Others:
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/Store/:StoreId', {
templateUrl: function(params){return 'webPages/Stores.php?storeID=' + params.StoreId;},
controller: 'storeParseData'
}).
otherwise({ redirectTo:'/Home' });
}]);
.when('/:storeId/private', {
templateUrl: function(params) {return 'webPages/Stores' + params.storeId;},
controller: 'storeParseData'
})
.when('/Store/:StoreId', {
templateUrl: 'path/to/your/template/index.html',
controller: 'MyController'
})
Then in MyController to read the parameter do
$scope.store_id = $routeParams.storeId;
