问题描述
qAnswersR[90430] = [];
qAnswersR[90430].push("[math]k: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]");
我需要将值变成变量,但是当我将console.log出来像这样的数组:
And I need to get the value into variable, but when I console.log out the array like this:
console.log(qAnswersR[90430]);
我得到: [math] k:rac {(x + 20)^ {2}} {256} + rac {(y-15)^ {2}} {81} = 1 [/ math],[数学] k:81(x + 20)^ {2} 256(y-15)^ {2} = 20736 [/ math]
I get: [math]k: rac{(x+20)^{2}}{256}+rac{(y-15)^{2}}{81}=1[/math],[math]k: 81(x+20)^{2}+256(y-15)^{2}=20736[/math]
但转义标记\
消失,但我需要它,我该怎么办?
But the escape tag "\"
disappears, but I need it there, what should I do?
推荐答案
但转义标记\消失,但我需要它,我该怎么办?
But the escape tag "\" disappears, but I need it there, what should I do?
您需要转义反斜杠,即使用 \\
而不是 \
:
You need to escape the backslash, i.e., use \\
instead of just \
:
"[math]k: \\frac{(x+20)^{2}}{256}+\\frac{(y-15)^{2}}{81}=1[/math]"
