我正在使用角度js应用程序,我需要动态创建带有按钮的文本框,这意味着
<div class="col-sm-4 type7" style="font-size:14px;">
<div style="margin-bottom:5px;">NDC9</div>
<input type="text" name="ndc9" class="form-control txtBoxEdit" ng-model="ndc9">
</div>
<div class="col-sm-4 type7 " style="font-size:14px;">
<div style="padding-top:20px; display:block">
<span class="red" id="delete" ng-class="{'disabled' : 'true'}">Delete</span> <span>Cancel </span> <span id="addRow" style="cursor:pointer" ng-click="ndcCheck(0)">Add </span>
</div>
</div>
这将创建一个
我将在上面的文本框中输入一些值并单击“添加”,需要在下一行创建相同的控件集,这意味着(需要使用输入的值再次创建带有上述3个按钮的文本框)。
最后我想获得所有输入的值。我怎样才能在角度js中实现这一点

您可以将ng-repeat与关联数组一起使用。添加基本上会将模型值推送到数组,并且还是数组中的空对象。
<div ng-repeat ="ndc in NDCarray">
<div class="col-sm-4 type7" style="font-size:14px;">
<div style="margin-bottom:5px;">NDC9</div>
<input type="text" name="ndc9" class="form-control txtBoxEdit" ng-model="ndc.val">
</div>
</div>
<div class="col-sm-4 type7 " style="font-size:14px;">
<div style="padding-top:20px; display:block">
<span class="red" id="delete" ng-class="{'disabled' : 'true'}" ng-click="NDCdelete($index)">Delete</span>
<span>Cancel </span>
<span id="addRow" style="cursor:pointer" ng-click="NDCadd ()">Add </span>
</div>
</div>
</div>
在控制器中:
$scope.NDCarray = [{val: ''}];
$scope.NDCadd = function() {
$scope.NDCarray.unshift(
{val: ''}
);
};
$scope.NDCdelete = function(index) {
$scope.NDCarray.splice(index, 1);
};
