Question

我已经测试了这个：

this.changedValue = document.getElementById("processID");
this.changedValueString = this.changedValue.value;
console.log("[INFO] Choosen processID: >" + this.changedValueString + "<");

不幸的是，我通过logcat获得了这个：

[INFO：CONSOLE（56878）]“[INFO]选择processID：＆gt; undefined＆lt;”

在你的输入元素中使用[（ngModel）]，如下所示，

>>> fp = open('xyz', 'r')
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
FileNotFoundError: [Errno 2] No such file or directory: 'xyz'
>>>
>>> # or with `with`:
... with open('xyz', 'r') as fp:
...     fp.readlnes()
...
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
FileNotFoundError: [Errno 2] No such file or directory: 'xyz'
>>>

并在你的component.ts中，

<input type="text" [(ngModel)]="inputValue" />
