用双引号包装javascript变量

Question

I've the following code with a string inside a js template literal.

`${currentType} ${objProp} = ${value};`

I want to wrap the ${value} with double quotes when it prints. How can I achieve this?

Answer 1

因为您使用的是ES6字符串模板，所以您可以在模板中使用双引号（ " ）或单引号（ ' ）。因此，这应该有效：

`${currentType} ${objProp} = "${value};"`

Answer 2

 let currentType = "hello"; let objProp = "world"; let value = "hi"; let a = `${currentType} ${objProp} = "${value}";` console.log(a) 

Just use the double quote surrounding your ${value}

UPDATES:

Just to try out to prove that it can supports double quoted string as below

 let value = '"hi"'; let a = `${value}`; console.log(a) let value2 = "\\"hi\\""; let a2 = `${value2}`; console.log(a2) 

Answer 3

`${currentType} ${objProp} = ${JSON.stringify(value)};`

Using JSON.stringify will do the right thing for all JS primitives, quoting strings, and correctly formatting objects and arrays.

EDIT because so many of other answerers seem to be missing the point:

 let currentType = 'string'; let objProp = 'actor'; let value = 'Dwayne "The Rock" Johnson'; let bad = `${currentType} ${objProp} = "${value}";` console.log(bad); // string actor = "Dwayne "The Rock" Johnson"; let good = `${currentType} ${objProp} = ${JSON.stringify(value)};` console.log(good); // string actor = "Dwayne \\"The Rock\\" Johnson"; 

Answer 4

Just wrapping ${value} inside double quotes does not seem to be a problem:

 var currentType = 11; var objProp = "test"; var value = 33; var templateVar = `${currentType} ${objProp} = "${value}";` console.log(templateVar); 

Answer 5

Here is a snippet....

 let val = "1243" let k = `"${val}"` console.log(k)
