问题描述
限时送ChatGPT账号..可以使用函数作为 templateUrl.$routeProvider 的官方文档指出:
It's possible to use a function as the templateUrl. The official documentation for $routeProvider states:
templateUrl – {string=|function()=}
templateUrl – {string=|function()=}
$routeProvider 官方文档
在javascript中,函数的语法如下:
In javascript, a function has the syntax of:
function() {code here}
但文档显示:
function()=
使用 function()=Code Here
不起作用.在 angularjs 路由中为 templateUrl 使用函数的语法是什么?
Using function()=Code Here
doesn't work. What is the syntax for using a function for the templateUrl in angularjs routing?
如果我使用类似的东西:
If I use something like:
when('/Store/:StoreId', {
templateUrl: function()=webPages/Stores.php?storeID=' + :StoreId,
controller: 'storeParseData'
这不起作用.我猜 :StoreId
的 URL 匹配会自动存储在 $routeProvider
中.我曾尝试以各种不同的方式使用 $scope
、$location
和 $routeProvider
,但都没有成功.我正在寻找将 URL # hash id 传递给 templateUrl 的最简单、最直接的方法.
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.
我需要将动态信息注入到 templateUrl 中的原因是我加载的页面是一个 PHP
文件,它在加载时运行 PHP 代码.PHP
代码从哈希 # URL 中检索信息.在控制器中检索 :StoreId
对我没有帮助.我希望 PHP
文件从 server side
而不是 front end
JavaScript 控制器检索数据.
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.
<?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/.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.
$storeListings = file_get_contents('https://NameOfDataURLHere/'.$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/'.$catToGetItemFrom.'/'.$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);
}
?>
使用 PHP 将数据注入 DIV 以供以后检索:
<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($storeListingsData);?></div>
解决方案 - 在他人的帮助下:
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/Store/:StoreId', {
templateUrl: function(params){return 'webPages/Stores.php?storeID=' + params.StoreId;},
controller: 'storeParseData'
}).
otherwise({ redirectTo:'/Home' });
}]);
推荐答案
.when('/:storeId/private', {
templateUrl: function(params) {return 'webPages/Stores' + params.storeId;},
controller: 'storeParseData'
})
