[英]Cannot read property of undefined error
I am trying to use an array to get a specific result but i get the error cannot read property of undefined but when i console log that same property i get my result here is my code : 我正在尝试使用数组来获取特定的结果,但是我得到的错误无法读取未定义的属性,但是当我控制台登录该属性时,我得到的结果是我的代码:
for (var j=0;j<$scope.ftListe.length;j++){
if(task[j].projet_id==id){
if(temp!=task[j].NomTache)
temptache.push(task[j]);
tempcol.push(lecollaborateur[j]);
}
temp=task[j].NomTache;
}
$scope.temptache=temptache;
$scope.tempcol=tempcol;
for(var i=0; i<temptache.length;i++){
for (var k=0;k<$scope.ftListe.length;i++){
console.log("l'id de la tache: "+temptache[i].IdTache);
if(temptache[i].IdTache==$scope.ftListe[k].tacheid){
temps = temps+$scope.ftListe[k].TempsPasse;
passe= passe+$scope.ftListe[k].TempsPasse * lecollaborateur[k].CoutParJour;
}
}
tempsAr.push(temps);
passeAr.push(passe);
temps=0; passe=0;
}
The property I get the error from is IdTache
, what am I doing wrong? 我从中收到错误的属性是IdTache
,我在做什么错?
Please take a look at the following lines: 请看以下几行:
for(var i=0; i<temptache.length;i++){
for (var k=0;k<$scope.ftListe.length;i++){
Note that in the inner for
loop, you increment the i
variable ( i++
) instead of k
. 请注意,在内部for
循环中,将i
变量( i++
)而不是k
递增。 So this make i
to get increment in the inner loop to an out of bounds offset. 因此,这使i
可以在内部循环中获得增量,以达到超出范围的偏移量。
The JS runtime error prevent your script from going into an Infinite loop - So when you stated that "when i console log that same property i get my result" it actually show the results up until the point where you're in the valid range of the temptache
array. JS运行时错误阻止您的脚本进入无限循环-因此,当您声明“当我用控制台记录相同的属性时,我得到我的结果”时,它实际上显示结果,直到达到您的有效范围为止temptache
数组。
You should fix it to: 您应该将其修复为:
for(var i=0; i<temptache.length;i++){
for (var k=0;k<$scope.ftListe.length;k++){
