不能得到使用AngularJs textarea的价值 [英] can't getting textarea value using AngularJs

问题描述

<tr class="labels">
    <td nowrap="nowrap">Address</td>
    <td nowrap="nowrap"><label for="tbAddress"></label>
        <textarea name="tbAddress" id="tbAddress" cols="39" rows="5" ng-model="$parent.tbAddress"></textarea>

    </td>

</tr>
<tr>
    <td>&nbsp;</td>
    <td align="right">
        <input type="submit" name="button" id="button" value="Submit Record" class="btns" />
        <input type="reset" name="button2" id="button2" value="Cancel" class="btns" />
    </td>
</tr>

我不能够使用AngularJS获得的textarea 值。所有输入文本字段通过除文本域控制器获得。我在做什么错了？

I'm not be able to get textarea value using AngularJS. All the input text fields are getting through the controller except the textarea. What am I doing wrong ?

alert($scope.tbAddress);
var thisData = {
    'name': $scope.tbFN,
    'company': $scope.tbCompany,
    'designation': $scope.tbDesignation,
    'email': $scope.tbEmail,
    'phone': $scope.tbPhone,
    'mobile': $scope.tbMobile,
    'address': $scope.tbAddress
};

这是警报不确定...

It's alert undefined...

推荐答案

如果您有警报（$ scope.tbAddress）; 定位在那里，当然它会最终成为未定义。一切都没有在这一点上被分配到 $ scope.tbaddress 。 （但也许你拥有了它前面定义，但它只是没有在code所示）。

If you have alert($scope.tbAddress); positioned right there, of course it'll end up as undefined. Nothing has been assigned to $scope.tbaddress at this point. (but maybe you have it defined earlier, but it's just not being shown in the code).

我居然没有一个问题得到它的工作。我裹着绑定到提交按钮功能的警报。我能够获得的价值。 见我的例子。

I actually didn't have a problem getting it to work. I wrapped the alert in a function that is bound to the submit button. I'm able to get the value. See my example.

我也改变了你的 $范围 A位的自由。它的建议，每个 ngModel 有一个。它的名字。因此，而不是 tbAddress 应该是 tb.address 。它有怎样的角度继承处理的事情。

I also took the liberty of changing your $scope a bit. It's recommended that every ngModel has a . in it's name. So rather than tbAddress it should be tb.address. It has to do with how angular inheritance is handled.
