在Angular JS Module中传递和获取DOM元素值
我是Angular JS的新手
我有一个HTML页面，加载这样一个JS文件
<script type="text/javascript" src="components/adf-widget-iframe/dist/adf-widget-iframe.min.js"></script> 该文件（adf-widget-iframe.min.js）内容如下
! function() { "use strict"; angular.module("adf.widget.iframe", ["adf.provider"]).config(["dashboardProvider", function(e) { e.widget("iframe", { title: "iframe", description: "Embed an external page into the dashboard", templateUrl: "{widgetsPath}/iframe/src/view.html", controller: "iframeController", controllerAs: "iframe", edit: { templateUrl: "{widgetsPath}/iframe/src/edit.html" }, config: { height: "420px" } }) }]).controller("iframeController", ["$sce", "config", function(e, r) { r.url && (this.url = e.trustAsResourceUrl(r.url)) }]), angular.module("adf.widget.iframe").run(["$templateCache", function(e) { e.put("{widgetsPath}/iframe/src/edit.html", "<form role=form><div class=form-group><label for=url>URL</label> <input type=url class=form-control id=url ng-model=config.url placeholder=http://www.example.com> //Here i need to put url from html page like from a text box. </div><div class=form-group><label for=url>Height</label> <input type=text class=form-control id=url ng-model=config.height></div></form>"), e.put("{widgetsPath}/iframe/src/view.html", '<div><div class="alert alert-info" ng-if=!config.url>Please insert a url in the widget configuration</div><iframe ng-if=iframe.url class=adf-iframe style="height: {{config.height}}" src={{iframe.url}}></iframe></div>') }]) }(window);
在上面的代码中，我必须从html页面获取一个值，并且需要放置在URL所示的位置（我已经注释掉了）。
有人可以帮我把文本框的数据放在URL的位置吗？
它的我的HTML文件

它是我引用的仪表板GUI，我正在使用这个仪表板的例子
https://github.com/angular-dashboard-framework/adf-dynamic-example
如果我正确理解问题，则在添加新的iframe时尝试传递当前页面的URL。
如果以上是真的，这是我的解决scheme：
- 将
$location注入到控制器中 - 获取当前页面的绝对path：
$location.$$absUrl - 在
$templateCache使用绝对path值
您既可以使用URLstring作为占位符input，也可以作为input值。 如果它被用作input值，则iframe被立即创build，因为通过原始devise它应该是空的
在GUI中，它将看起来像这样： 
adf-widget-iframe.js的内容 ：
(function(window, undefined) {'use strict'; angular.module('adf.widget.iframe', ['adf.provider']) .config(["dashboardProvider", function(dashboardProvider){ dashboardProvider .widget('iframe', { title: 'iframe', description: 'Embed an external page into the dashboard', templateUrl: '{widgetsPath}/iframe/src/view.html', controller: 'iframeController', controllerAs: 'iframe', edit: { templateUrl: '{widgetsPath}/iframe/src/edit.html' }, config: { height: '420px' } }); }]) .controller('iframeController', ["$sce", "config", "$location", function($sce, config, $location){ config.placeholder = $location.$$absUrl; if (config.url){ this.url = $sce.trustAsResourceUrl(config.url); } }]); angular.module("adf.widget.iframe").run(["$templateCache", function($templateCache) {$templateCache.put("{widgetsPath}/iframe/src/edit.html","<form role=form><div class=form-group><label for=url>URL</label> <input type=url class=form-control id=url ng-model=config.url placeholder={{config.placeholder}}></div><div class=form-group><label for=url>Height</label> <input type=text class=form-control id=url ng-model=config.height></div></form>"); $templateCache.put("{widgetsPath}/iframe/src/view.html","<div><div class=\"alert alert-info\" ng-if=!config.url>Please insert a url in the widget configuration</div><iframe ng-if=iframe.url class=adf-iframe style=\"height: {{config.height}}\" src={{iframe.url}}></iframe></div>");}]);})(window);
不要忘记实际导入没有缩小文件到index.html ：
<!-- iframe --> <script type="text/javascript" src="components/adf-widget-iframe/dist/adf-widget-iframe.js"></script>
