这是我的阵列推送:
import subprocess
import os
a=input(" ")
if(a>0):
subprocess.call(["php", "write.php"])
Traceback (most recent call last):
File "D:\PROGRAMS\xamkpp\htdocs\proba.py", line 5, in <module>
subprocess.call(["php", "write.php"])
File "C:\Python27\lib\subprocess.py", line 522, in call
return Popen(*popenargs, **kwargs).wait()
File "C:\Python27\lib\subprocess.py", line 710, in __init__
errread, errwrite)
File "C:\Python27\lib\subprocess.py", line 958, in _execute_child
startupinfo)
WindowsError: [Error 2] The system cannot find the file specified
我给navParams一个像这样的页面推送:
let results = this.allExercises[i];
this.dataArray.push(results);
我在我的主页中检索它们,如下所示:
this.navCtrl.push(HomePage, {
'exercisesDone': this.dataArray
});
在我的HTML中,我这样做:
constructor(public navCtrl: NavController, public params:NavParams) {
if(params.get("exercisesDone")){
this.exerciseIsDone = params.get("exercisesDone");
console.log('exerciseDone: ', this.exerciseIsDone);
}
}
以此为结果:
<p>{{ exerciseIsDone }}</p>
<div *ngFor="let b of exerciseIsDone; let i = index">{{ b }}</div>
如何打印数组的值?
