双击编辑

这个示例,可以实现双击编辑功能,双击文本时可以进入编辑模式,编辑完成后失去焦点或者按下回车键可以保存编辑内容。

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <script src="/user/js/angular-1.5.8.min.js"></script>
    <link rel="stylesheet" href="/css/bootstrap/5.3/bootstrap.min.css">
</head>
<body ng-app="MyModule">
    <div class="mb-3 row" ti-editable-input>
        <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
        <div class="col-sm-10">
            <input type="text" readonly  class="form-control-plaintext" id="staticEmail" value="email@example.com">
        </div>
    </div>
</body>
<script>
    var myModule = angular.module("MyModule", []);

    //注射器加载完所有模块时,此方法执行一次
    myModule.run(function () {});

    myModule.directive("tiEditableInput", function () {
        return {
            restrict: 'A',
            link: function (scope, element) {
                var inputElement = element.find('input');
                element.on('dblclick', function() {
                    if (inputElement.length) {
                        inputElement.attr('readonly', false);
                        inputElement.removeClass('form-control-plaintext');
                        inputElement.addClass('form-control');
                        inputElement[0].focus();
                    }
                });
                inputElement.on('blur', function() {
                    restoreReadonly();
                });
                inputElement.on('keyup', function(event) {
                    if (event.keyCode === 13) { // 回车键的键码是13
                        restoreReadonly();
                    }
                });
                function restoreReadonly() {
                    if (!inputElement.attr('readonly')) {
                        inputElement.attr('readonly', true);
                        inputElement.removeClass('form-control');
                        inputElement.addClass('form-control-plaintext');
                    }
                }
            }
        };
    });

双击编辑,有确认和取消

双击之后,显示「确认」和「取消」按钮。
