html:
<div class="simulate-textarea" ng-model="view.text" contenteditable="true" placeholder="请输入内容"></div>
Angularjs指令:
/** * div模拟textarea输入框双向数据绑定指令 */ .directive('contenteditable', [function() { return { require: 'ngModel', link: function(scope, element, attrs, ctrl) { //view -> model element.bind('input', function() { scope.$apply(function() { ctrl.$setViewValue(element.html()); }); }); //model -> view ctrl.$render = function() { element.html(ctrl.$viewValue); }; } }; }
css:
.simulate-textarea { margin-left: 84px; display: inline-block; width: calc(100% - 84px); /*border: 1px solid #dddddd;*/ min-height:20px; _height: 20px; max-height: 120px; /*border-radius: 4px;*/ /*padding: 4px 6px;*/ outline: 0; word-break:break-all; word-wrap: break-word; white-space: pre-wrap; overflow-x: hidden; overflow-y: auto; line-height: 20px; font-size: 12px; }
