Question

我是angularJS的新手

我使用带有ui-router和slickgrid的angularJS 我尝试通过单击图像调用方法来调用Web服务并删除行

我有这个控制器：

app.controller('customerController', ['$scope', '$compile', 'CustomerService',      function ($scope, $compile, CustomerService) {
    // function to get customers
    $scope.getCustomers = function () {
        CustomerService.getCustomers($("#userId").val(), $scope.getArchived).then(function (customers) {
            dataView.beginUpdate();
            dataView.setItems(customers);
            dataView.endUpdate();
            grid.invalidate();
        }, function (reason) {
            noty({ text: reason, type: 'error' });
        });
    }
    // function to archive customer
    $scope.archiveCustomer = function(customerId) {
        if (confirm(translate("LBL_DELETE_CUSTOMER_CONFIRMATION"))) {
            CustomerService.archiveCustomer(customerId).then(function () {
                $scope.getCustomers();
            }, function (reason) {
                   noty({ text: reason, type: 'error' });
            });
        }
        return false;
    }

    // create grid
    var dataView,
        grid;
    var options = {
        enableCellNavigation: true,
        enableColumnReorder: false,
        autoHeight: true
    };

    var columns = [
        { id: "id", name: "", field: "id", width: 20, formatter: deleteFormatter, cssClass: "centeredColumn" },
        { id: "customer", name: translate("Customer"), field: "customer", width: 250 }
    ];

    function deleteFormatter(row, cell, value, columnDef, dataContext) {
        html = "<img src='images/delete.gif' alt='" + translate("LBL_DELETE_CUSTOMER") + "' style='cursor:pointer;' ng-click='archiveCustomer(" + dataContext.id + ");' />";
        linker = $compile(angular.element(html));
        htmlElements = linker($scope);
        html = htmlElements[0].outerHTML;
        return html;
    }

dataView = new Slick.Data.DataView({ inlineFilters: true });
    grid = new Slick.Grid("#customersGrid", dataView, columns, options);

    $scope.getCustomers();
}]);

我的问题是ng-click由deleteFormatter添加的img元素。怎么了？我看到了带有指令的样品，但在我看来并不清楚......你能点亮我吗？

修改

尝试使用asyncPostRender但未成功：列定义：

var columns = [
        { id: "id", name: "", field: "id", width: 20, formatter: asyncFormatter, asyncPostRender: deleteRender, cssClass: "centeredColumn" },
        { id: "customer", name: translate("Customer"), field: "customer", width: 250 }
    ];

格式化并渲染：

function asyncFormatter(row, cell, value, columnDef, dataContext) {
    return "Data loading...";
}

function deleteRender(cellNode, row, dataContext, colDef) {
    html = "<img src='images/delete.gif' alt='" + translate("LBL_DELETE_CUSTOMER") + "' style='cursor:pointer;' ng-click='archiveCustomer(" + dataContext.id + ");' />";
    linker = $compile(angular.element(html));
    htmlElements = linker($scope);
    $(cellNode).empty()
    cellNode.innerHTML = htmlElements[0].outerHTML;
}

<强>已更新

＆＃34;格式化＆＃34;似乎只是给定列的配置函数。您需要为该列使用渲染函数，例如＆＃34; asyncPostRender＆＃34;。请参阅this example。

您的新元素（删除img）超出任何Angular范围。你需要在网格行的渲染事件中将它编译成Angular。

在Kursad Gulseven（谢谢你）和this post

的帮助下回答

控制器声明：

app.controller('customerController', ['$scope', '$rootScope', '$compile', '$interpolate', 'CustomerService', function ($scope, $rootScope, $compile, $interpolate, CustomerService) {

列定义：

var columns = [
    { id: "id", name: "", field: "id", width: 20, formatter: deleteFormatter, asyncPostRender: deleteRender, cssClass: "centeredColumn" },
    { id: "customer", name: translate("Customer"), field: "customer", width: 250 }
];

格式化并渲染：

function deleteFormatter(row, cell, value, columnDef, dataContext) {
    return "<img src='images/delete.gif' alt='delete' style='cursor:pointer;' ng-click='archiveCustomer(" + dataContext.id + ");' />";
}

function deleteRender(cellNode, row, dataContext, colDef) {
    // compile the html with angular to get ng-click with the correct scope
    var interpolated = $interpolate($(cellNode).html())($scope);
    var linker = $compile(interpolated);
    var htmlElements = linker($scope);
    $(cellNode).empty()
    $(cellNode).append(htmlElements);
}

归档客户功能：

$scope.archiveCustomer = function (customerId) {
    if (confirm(translate("LBL_DELETE_CUSTOMER_CONFIRMATION"))) {
        CustomerService.archiveCustomer(customerId).then(function () {
            $scope.getCustomers();
        }, function (reason) {
            noty({ text: reason, type: 'error' });
        });
    }
}

在slickgrid格式化程序中单击ng-click无效
