使用 AngularJS 的数据表中的单元格按钮 [英] Cell button in datatables using AngularJS

问题描述

我正在使用 angularjs 构建网站，并且正在从网络服务获取数据.我需要将该数据填充到数据表并为每一行创建一个编辑按钮.经过一番调查，我想出了 this

问题是 ng-click 不起作用，可能是因为我需要编译我注入表格单元格的 html.我已经以多种方式尝试过，但不幸的是，我对 angular 还是很陌生，我似乎不明白我如何才能做到这一点.我真的需要这方面的帮助.

这是我的指令:

dialogApp.directive('myTable', function ($compile) {返回 {限制:'E，A，C'，链接:函数(范围、元素、属性、控制器){var dataTable = element.dataTable(scope.options);scope.$watch('options.aaData', handleModelUpdates, true);函数 handleModelUpdates(newData) {var 数据 = 新数据 ||空值;如果(数据){数据表.fnClearTable();dataTable.fnAddData(data);}}},范围: {选项:="}};});

控制器:

dialogApp.controller('DataTableTestController', ['$scope', function($scope){$scope.coisas = "coisas";$scope.botaoEdit = function(a){控制台日志(一)；};$scope.options = {"sDom": '<"H"lf>t<"F"ip>',bStateSave":真，bPaginate":假，bLengthChange":假，bFilter":真，bSort":真，bInfo":真，bAutoWidth":假，"sPaginationType": "full_numbers",ao 列:[{"sTitle": "姓名"}, {"sTitle": "价格"}, {"sTitle": "类别"}, {"sTitle": "动作"}， 空值]，"asorting": [[ 0, "asc" ]],aoColumnDefs: [{ "bSortable": true, "aTargets": [0] },{ "bSortable": false, "aTargets": [1,2,3,4] }],bJQueryUI:真，数据:[]};var dbStuff = [{"name": "Stuff1",价格":10000000.00，"description": "昂贵的东西","想要":"买"},{"name": "Stuff2",价格":20000000.00，"description": "哦，我的...",想要":有钱"}]for(dbStuff 中的 var 键){$scope.options.aaData.push([dbStuff[key].name,dbStuff[key].price,dbStuff[key].description,dbStuff[key].wanna,"<button ng-click=\"botaoEdit("+dbStuff[key].name+")\">测试按钮</button>"]);}$scope.counter = 0;}])

还有 HTML:

<link type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/themes/redmond/jquery-ui.css" rel="样式表"/><link rel="stylesheet" type="text/css" href="http://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.8.2/css/jquery.dataTables.css"><div ng-app="tableExample"><div ng-controller="DataTableTestController">{{ coisas }}<table my-table options="options" class="jquery-datatables"></table>

解决方案

是的，你说得对，ng-click 指令不是由 angular 编译的.所以最直接的方法是使用onclick listener:

 "<button onclick=\"angular.element(this).scope().botaoEdit('"+dbStuff[key].name+"')\">测试按钮</button>"

不要忘记添加引号:botaoEdit('')，在您的小提琴中，您尝试访问 Stuff1 变量 :)

最后，我认为最好的方法是使用一些网格插件或 ng-repeat，它们会在收到数据时为您的表构建行.在这种方法中 ng-click 在您的行中可以正常工作.

I'm building a website using angularjs and i'm getting data from a webservice. I need to populate that data to a datatable and create an edit button for each row. After some investigation i came up with this

The problem is that the ng-click isn't working probably because i need to compile the html i injected to the table cell. I've tried that in several ways but unfortunately i'm still very new to angular and i don't seem to understand how i can accomplish that. I really need help with this one.

This is my directive:

dialogApp.directive('myTable', function ($compile) {
return {
    restrict: 'E, A, C',
    link: function (scope, element, attrs, controller) {
        var dataTable = element.dataTable(scope.options);

        scope.$watch('options.aaData', handleModelUpdates, true);

        function handleModelUpdates(newData) {
            var data = newData || null;
            if (data) {
                dataTable.fnClearTable();
                dataTable.fnAddData(data);
            }
        }
    },
    scope: {
        options: "="
    }
};}); 

The controller:

dialogApp.controller('DataTableTestController', ['$scope', function($scope){
$scope.coisas = "coisas";
$scope.botaoEdit = function(a){
    console.log(a);
};

$scope.options = {
    "sDom": '<"H"lf>t<"F"ip>',
    "bStateSave": true,
    "bPaginate": false,
    "bLengthChange": false,
    "bFilter": true,
    "bSort": true,
    "bInfo": true,
    "bAutoWidth": false,
    "sPaginationType": "full_numbers",
    aoColumns: [{
        "sTitle": "name"
    }, {
        "sTitle": "price"
    }, {
        "sTitle": "category"
    }, {
        "sTitle": "action"
    }, null],
    "aaSorting": [[ 0, "asc" ]],
    aoColumnDefs: [
        { "bSortable": true, "aTargets": [0] },
        { "bSortable": false, "aTargets": [1,2,3,4] }
    ],
    bJQueryUI: true,
    aaData: []
};

var dbStuff = [
    {
        "name": "Stuff1",
        "price": 10000000.00,
        "description": "Expensive Stuff",
        "wanna":"buy"
    },
    {
        "name": "Stuff2",
        "price": 20000000.00,
        "description": "Oh my...",
        "wanna":"have money"
    }
]

for (var key in dbStuff){
    $scope.options.aaData.push([dbStuff[key].name,
                                dbStuff[key].price,
                                dbStuff[key].description,
                                dbStuff[key].wanna,
                                "<button ng-click=\"botaoEdit("+dbStuff[key].name+")\">test button</button>"
                               ]);
}

$scope.counter = 0; }])

And the HTML:

<link type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/themes/redmond/jquery-ui.css" rel="stylesheet" />
<link rel="stylesheet" type="text/css" href="http://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.8.2/css/jquery.dataTables.css">

<div ng-app="tableExample">
    <div ng-controller="DataTableTestController">   
        {{ coisas }}
        <table my-table options="options" class="jquery-datatables"></table>
    </div>
</div>

解决方案

Yes, you're right, ng-click directive wasn't compiled by angular. So the most straight forward way is to use onclick listener:

 "<button onclick=\"angular.element(this).scope().botaoEdit('"+dbStuff[key].name+"')\">test button</button>"

Don't forget to add quotes: botaoEdit(''), in your fiddle you try to access Stuff1 variable :)

In the end, I think the best way is to use some grid plugin or ng-repeat, that would build rows for your table when data recieved. In this approach ng-click in your rows will work fine.
