【问题描述】:
按照here 提供的示例,我已经按照要求安装了滑块
index.html
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Rating</title>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.0/themes/smoothness/jquery-ui.css">
<script data-require="angular.js@1.4.0-beta.6" data-semver="1.4.0-beta.6" src="https://code.angularjs.org/1.4.0-beta.6/angular.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.0/jquery-ui.min.js"></script>
<script src="test.js"></script>
</head>
<body ng-app="myApp">
<div ng-controller="testController">
<table>
<tr>
<td>Amount:</td>
<td><div slider ng-model="amount" style="width:200px;"></div></td>
<td><input type= "text" ng-model="amount" id="txtAmount"></td>
</tr>
</table>
</div>
</body>
</html>
test.js
var myApp = angular.module("myApp", []);
myApp.controller("testController", function($scope, $http){
$scope.amount = 1;
}); //end controller
myApp.directive('slider', function() {
return {
restrict: 'A',
scope: {
ngModel: '='
},
link: function(scope, elem, attrs) {
console.log(scope.ngModel);
return $(elem).slider({
range: "min",
animate: true,
value: scope.ngModel,
slide: function(event, ui) {
return scope.$apply(function(){
scope.ngModel = ui.value;
});
}
});
}
};
});
问题是
a) 最大范围不能设置超过 100。假设我希望最小值为 1,最大值为 1000。如何做到这一点?
b) 没有发生双向绑定。假设我将“txtAmount”的值设置为 50,那么滑块应该指向该值(50)
