Protractor Get Model Value
提问by Sumit
I am new to ProtractorJS. What I am trying to do is trying to get the value of a disabled input element. This input element is bound to a model. Initially this input element is empty; then after some action the model value is updated (and thus displayed in input element). I need to get that value, how can I do that ?
我是 ProtractorJS 的新手。我想要做的是尝试获取禁用输入元素的值。此输入元素绑定到模型。最初这个输入元素是空的；然后在一些操作之后更新模型值（并因此显示在输入元素中）。我需要获得那个价值，我该怎么做？
My input element is:
我的输入元素是：
<input class="form-control ng-pristine ng-valid" style="font-size: 11px;" disabled="disabled" type="text" ng-model="Promotion.PrometricID">
I am trying to fetch value by:
我试图通过以下方式获取价值：
element(by.model("Promotion.PrometricID")).getAttribute('value');
But whenever I write the value in console it gives me "[object] [object]".
但是每当我在控制台中写入值时，它都会给我“[object] [object]”。
Can anyone please tell me how to find value in this text box or in model ?
谁能告诉我如何在此文本框或模型中找到值？

It is just because getAttribute()returns a promise.
这只是因为getAttribute()返回一个 promise。
You need to resolve itif you want to see the result on the console:
如果你想在控制台上看到结果，你需要解决它：
var elm = element(by.model("Promotion.PrometricID"));
elm.getAttribute('value').then(function (value) {
console.log(value);
});
FYI, exploring The WebDriver Control Flowdocumentation page should clear things up.
仅供参考，探索WebDriver 控制流文档页面应该可以解决问题。

element(by.binding('Promotion.PrometricID')).getText().then(function (value) {
console.log(value);
