Jqueryで電卓を作成しているのですが、とある部分でうまく対応できません。
|
2
|
+
|
3
|
+
具体的には
|
4
|
+
|
5
|
+
1)第1項の数値を入力し
|
6
|
+
|
7
|
+
2)四則の計算を押した
|
8
|
+
|
9
|
+
3)第2項の数値を入力する
|
10
|
+
|
11
|
+
|
12
|
+
|
13
|
+
の2と3の間の箇所なのですが、
|
14
|
+
|
15
|
+
下記のコードの通り、四則計算について、値が保持されtrueであれば
|
16
|
+
|
17
|
+
var $num_2に押されたテキストが保持され、複数の値が押された場合には
|
18
|
+
|
19
|
+
$display_text2にjoinされた数値が保持されるイメージで作成しました。
|
20
|

21

22

23

if ($calculator) {

26
|
+
|
27
|

$('#display').text("");
|
28
|
+
|
29
|

var $num_2 =$(this).text();
|
30
|
+
|
31
|

console.log($num_2);
|
32
|

|
33
|

|
34
|

|
35
|
+
if ($num_2==1||$num_2==2||$num_2==3||$num_2==4||$num_2==5||$num_2==6||$num_2==7||$num_2==8||$num_2==9||$num_2==0) {
|
36
|
+
|
37
|
+
ary2.push($num_2);
|
38
|

|
39
|

$display_text2 =ary2.join("");
|
40
|

$('#display').text($display_text2);
|
42
|

console.log($display_text2);

|
+
}
|
48
|
+
|
49
|
+
|
50
|
+
|
51
|

しかし実際には
|
52
|
+
|
53
|
+
console.log($num_2);について出力されません。
|
54
|
+
|
55

|

何か良い方法やアドバイスを頂ければと思います。
