How can I force ng-click to take precedence over a

问题:

When I click the save button it triggers an ng-blur event, how can I make the buttons ng-click event to trigger instead? I still want the ng-blur event to trigger if I click outsida the button or input field.

angular.module('MyApp', [])

.filter("placeholder", function(){
    return function (text, length, end) {
        //console.log(typeof text, text, length);
        if(typeof text === 'undefined' || text == ''){
            text = 'Click to edit...';
        }
        return text;
    };
})

.directive("inlineEdit", function($compile, $q){
    return {
        restrict: "A",
        replace: true,
        template: function(tElement, tAttrs){
            var modelStr = tAttrs.inlineEdit, optionsStr = tAttrs.options, modelXtra = '', editElStr = '';
            if(tAttrs.type === 'selectbox'){
                modelXtra = '.value';
                editElStr = '<select ng-show="editMode" ng-blur="endEdit(\''+modelStr+'\')" ng-model="'+modelStr+'" ng-options="a.value for a in '+optionsStr+'"></select>';
            }else if(tAttrs.type === 'textarea'){
                editElStr = '<textarea ng-show="editMode" ng-blur="endEdit(\''+modelStr+'\')" ng-model="'+modelStr+'"></textarea>';
            }else{
                editElStr = '<input type="text" ng-show="editMode" ng-blur="endEdit(\''+modelStr+'\')" ng-model="'+modelStr+'" />';
            }
            return '<div class="body">'+
                       '<span ng-hide="editMode" ng-click="startEdit(\''+modelStr+'\', \''+optionsStr+'\')" ng-bind="'+modelStr+modelXtra+' | placeholder"></span>'+
                       editElStr+'<button ng-show="editMode" ng-click="save()">save</button>'+
                   '</div>';
        },
        scope: true,
        controller: function($scope){
            $scope.editMode = false;
            $scope.save = function(){
                console.log("Saving...");
                $scope.editMode = false;
            };
            $scope.startEdit = function(modelStr, optionsStr){
                console.log("Start edit mode...");
                // Store original value, to be restored if not saving...
                $scope.origValue = $scope.$eval(modelStr);
                // If selectbox and no initial value, do init to first option
                if(typeof $scope.origValue === 'object' && typeof $scope.origValue.value !== 'string'){
                    $scope.$eval(modelStr+'='+optionsStr+'[0]');
                }
                // Turn on edit mode

                console.log("End edit mode...");
                // Restore original value
                $scope.$eval(modelStr+'=origValue');

                $scope.editMode = false;
            };
        }
    }

.controller("UserAdminCtrl", function($scope){
    $scope.options = {};
    $scope.options.cars = [
        { "key": 0, "value": "Audi" },
        { "key": 1, "value": "BMW" },
        { "key": 2, "value": "Volvo" }

    $scope.data_copy = {
        user: {
            user_id: 'sevaxahe',

回答1:

Instead of ng-click, use ng-mousedown. Mousedown events get fired before blur events.

However, the handled mousedown might un-focus your field without the blur event being fired. If you then click outside the box, the blur event won't be fired (because the field is already blurred), so after setting focus, you might need to re-focus the field manually - see How to set focus on input field?

Note that by using this approach, the button can also be triggered using right-click (thanks Alexandros Vellis!) as you can see in this official example.

回答2:

Don't use ng-blur then, bind the $document with click event to stop edit mode. And remember to unbind the event when the scope is destroyed.

回答3:

If you want to run click event functionality before ng-blur than write your functionality in ng-mousedown event instead ng-click.
