Angularjs 将UI网格行数据发送到Textarea,angularjs,selection,Angularjs,Selection,以下是我的角度脚本： angular.module('app', ['ngTouch', 'ui.grid', 'ui.grid.selection']) .controller('MainCtrl', ['$scope', function ($scope) { var vm = this; vm.gridOptions = { multiSelect:false}; vm.reset = reset; function reset() { vm.gridOpt

复制

我想在

textarea

中显示所选行。一次选择行，但无法在文本区域显示数据？

由于我是初学者，欢迎提出任何建议。

请突出显示代码的相关部分，不要提供完整的代码。我想将选中的行从UI网格显示到textarea中。这不是我要求的。您似乎没有在控制器中为

vm.copy

编写任何内容。我之前写过类似于在textarea中显示选中行的内容：function copy（）{var v=$scope.mySelections；var z=document.getElementById（“t”）；z.innerHTML=v；}请突出显示代码的相关部分，不要提供完整代码。我想将选定行从UI网格显示到textarea。这不是我要求的。您似乎没有在控制器中为

vm.copy

编写任何内容。我之前编写过类似于：function copy（）的文本区域中显示选定行的代码{var v=$scope.mySelections；var z=document.getElementById（“t”）；z.innerHTML=v；}
