I am trying to use angularjs dynamic form elements but when I type something in inputs, there are appearing many special characters []"":
and field, value
.etc in textarea, I just want to see in textarea what I wrote in inputs ,
this is what I am working on it http://plnkr.co/edit/JbjqjAoQ3odBhXF1a13r?p=preview
sorry for my poor english,,,
问题是您正在渲染{{inputs}}并且输入是一个数组。
What Chris Story says is correct. You are trying to model the text value of the <textarea>
to an array of objects, inputs
If you are just trying to display the results like it seems, a <textarea>
is not the way to go. You can display them in a simple list, like this:
<ul>
<li ng-repeat="input in inputs">{{input.field}} = {{input.value}}</li>
</ul>
EDIT
To display it in a <textarea>
, you will need to store the list as string to use. This can be done by appending each item into a single string each time there is a change to an input value using ng-change
.
Change the inputs to utilize the ng-change:
<div ng-repeat="input in inputs">
<input type="text" ng-model="input.field" ng-change="inputChanged()" />
<input type="text" ng-model="input.value" ng-change="inputChanged()" />
<button ng-click="removeInput($index); inputChanged()">Remove</button>
</div>
And create the function that is called to maintain the string:
$scope.inputChanged = function() {
$scope.listString = "";
for(var i = 0; i < $scope.inputs.length; i++) {
var field = $scope.inputs[i].field;
var value = $scope.inputs[i].value;
$scope.listString += field + " = " + value + "; ";
}
}
And finally, use this $scope.listString
in the <textarea>
:
<textarea rows="22" cols="55" ng-model="listString"></textarea>
I have forked your Plunkr here
The behavior does not make much sense from a UX perspective, but this seems to match your requirement. An option that might make sense is to add disabled="true"
to the <textarea>
so it can not be edited.
