问题描述

这是可以使用函数作为templateUrl。为$ routeProvider官方文档声明:


  

templateUrl - {字符串= |函数()=}


$ routeProvider官方文档

在JavaScript中,一个函数的语法:

 函数(){code}在这里

但文档显示:

 函数()=

使用函数()= code以下不起作用。哪些是angularjs路由使用的templateUrl一个函数的语法?

如果我用的是这样的:

 时,('/存储/:STOREID',{
      templateUrl:函数()=网页/ Stores.php STOREID ='+:STOREID,
      控制器:'storeParseData

这是行不通的。我想这对的URL匹配:STOREID 自动存储在 $ routeProvider 。我已经使用 $范围 $位置试过了, $ routeProvider 在没有成功的各种不同的方式。我在寻找一个URL#散列ID传递给templateUrl最简单,最直接的方式。

我需要注入动态信息到templateUrl究其原因,是因为我在页面加载是加载时运行PHP code一 PHP 文件。在 PHP code检索哈希#URL信息。检索:在控制器STOREID 不会帮助我。我想在 PHP 文件从服务器端,而不是前端检索数据 JavaScript的控制器。

下面是PHP code:

 < PHP
//有两种基本方案。 1)获取所有商店的名称来填充店铺列表
// 2)获取所有的帖子从一个特定的用户,(存储)
//如果URL有'猫=什么',然后让所有的存储数据
//如果URL没有'猫=什么',然后获取存储数据。//只拿到店里的名字,如果DIV与商店的名称是空的,否则
//刚刚拿到专卖店上市。$ storeNames =的file_get_contents('https://NameOfDataURLHere.com/.json');//这是previously投入URL字符串结尾信息被分析有以下code。
$ urlPiece = $ _ SERVER ['REQUEST_URI'];
回声(URL海贼王:$ urlPiece);
//发现在URL字符串搜索标准的第一个字符的位置:STOREID ='。
//首先,URL被检查'STOREID ='。如果'STOREID ='在URL退出,那么页路由注入'STOREID ='
//作为一个参数字符串传递。如果没有参数传递,然后'STOREID ='字符串。
$ posOfEqualSign = strrpos($ urlPieceSTOREID =);
回声(< BR>中);
回声(posOfEqualSign:$ posOfEqualSign);
回声(< BR>中);
//如果找到字符串STOREID =',没关系继续。如果(使用isset($ posOfEqualSign)及&放大器; strlen的($ posOfEqualSign)大于0){
  //如果你想默认要去字符串的结尾在PHP SUBSTR函数并不需要一个长名称。
  $ STOREID = SUBSTR($ urlPiece,$ posOfEqualSign + 8);
  回声(STOREID长:.strlen($ STOREID));
  回声(< BR>中);
  回声(STOREID:$ STOREID);
  回声(< BR>中);
}如果(使用isset($ STOREID)及&放大器; strlen的($ STOREID)→3){
  //获取店里的所有目录出来的房源数据库与存储ID
  //商店ID从URL检索。当用户点击店名商店ID投入的URL。
  $ storeListings =的file_get_contents('https://NameOfDataURLHere.com/'.$storeID.'/.json');
  $ listingsDe codeD = json_de code($ storeListings,真正的);  回声(storeListings:$ storeListings);
  回声(< BR>中);  如果(strlen的($ storeListings)→1){
  的foreach($ listingsDe codeD为$关键=> $值){
    。// $ keyValHere =\\$键\\;    //回声keyValHere。 $ keyValHere;
    回声< BR>< BR>中;
    回声等级1键:。 $关键;
    呼应'< BR>< BR>';    $ storeListingsData =阵列();    的foreach($值$ X => $ V){
        回声二级重点。 $ X;
        回声< BR>中;
        回声Lelvel 2值:。 $ V;
        回声< BR>中;
        $ specificListing = SUBSTR($ V,4);
        $ catToGetItemFrom = SUBSTR($ V,0,3);
        回声上市编号:'。 $ specificListing;
        回声< BR>中;
        回声'类别:'。 $ catToGetItemFrom;
        如果(strlen的($ catToGetItemFrom)大于0&放大器;&放大器; strlen的($ specificListing)→1){
          如果(ORD($ catToGetItemFrom)LT = 109){// ORD返回一个字符串的第一个字符的ASCII值
            $ whatDB =NameOfDBHere;
          }其他{
            $ whatDB =NameOfSecondDBHere;
          }
          $ oneStoreListing = file_get_contents('https://'.$whatDB.'.dataURL.com/'.$catToGetItemFrom.'/'.$specificListing.'/.json');
        }其他{
          $ oneStoreListing =;
          回声(一店清单:'$ oneStoreListing);
        }        如果(strlen的($ oneStoreListing)→1){
          //保存,直到循环完成增加单店上市到阵列。
          array_push($ storeListingsData,$ oneStoreListing);
        }
    }
  }
}呼应'< BR>';
回声(商店名称:'。$ storeNames);
回声('< BR>');
回声(一店清单:'$ storeListingsData);}
?>

数据注入DIV用PHP为以后的检索:

 < BR>< D​​IV ID =idCatName的风格=显示:内联?>< PHP的echo $ catToGetItemFrom;>< / DIV>
< BR>
< D​​IV ID =idStoreNames的风格=?显示:内联>< PHP的echo($ storeNames);>< / DIV>
< BR>
< D​​IV ID =idStoreData的风格=?显示:内联>< PHP的echo($ storeListingsData);>< / DIV>

解决方案 - 与一些帮助从其他:

  myApp.config(['$ routeProvider',
   功能($ routeProvider){$ routeProvider。
    当('/存储/:STOREID',{
        templateUrl:功能(PARAMS){回报?网页/ Stores.php STOREID ='+ params.StoreId;},
        控制器:'storeParseData
     })。
     否则({redirectTo:'/家庭'});
  }]);


解决方案

 。当('/:STOREID /私',{
    templateUrl:功能(PARAMS){回报网页/店'+ params.storeId;},
    控制器:'storeParseData
})

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' });
  }]);

解决方案

.when('/:storeId/private', {
    templateUrl: function(params) {return 'webPages/Stores' + params.storeId;},
    controller: 'storeParseData'
})
