How to make javascript ignore escape ( \ ) character?
提问by Mike
qAnswersR[90430] = [];
qAnswersR[90430].push("[math]k: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]");
And I need to get the value into variable, but when I console.log out the array like this:
我需要将值放入变量中，但是当我 console.log 像这样注销数组时：
console.log(qAnswersR[90430]);
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]
我得到： [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]
But the escape tag "\"disappears, but I need it there, what should I do?
但是转义标签"\"消失了，但我需要它，我该怎么办？

但是转义标签“\”消失了，但我在那里需要它，我该怎么办？
You need to escape the backslash, i.e., use \\instead of just \:
您需要转义反斜杠，即使用\\而不仅仅是\：
"[math]k: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]"

Escape the escape character, like \\a.
转义转义字符，例如\\a.

You can use tagged template literals
您可以使用标记的模板文字
var str = (s => s.raw)`[math]k: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]`[0]
The anonymous arrow function will serve as tag and s.rawcontains the original input
匿名箭头函数将作为标签并s.raw包含原始输入
