用javascript编码url而不编码& [英] encoding url in javascript not encoding &

问题描述

我正在用javascript编码以下字符串

encodeURI = "?qry=M & L";

这给了我一个输出

qry=m%20&%20l

因此，&" M & L中的来自未编码.我该怎么办?

解决方案

不对具有特殊含义的字符进行编码(保留 字符).以下示例显示了所有 URI方案"可能包含.

参考

encodeURI 不会编码以下特殊字符

A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

 let uri = "?qry=M & L"

console.log(encodeURI(uri)) 

因此您可以使用 encodeURIComponent ，这将对除这些字符之外的所有字符进行编码

A-Z a-z 0-9 - _ . ! ~ * ' ( )

 let uri = "?qry=M & L"

console.log(encodeURIComponent(uri)) 

I am encoding the following string in javascript

encodeURI = "?qry=M & L";

This give me an output

qry=m%20&%20l

So the "&" from M & L is not getting encoded. What should i do?

解决方案

Does not encode characters that have special meaning (reserved characters) for a URI. The following example shows all the parts that a URI "scheme" can possibly contain.

Reference

encodeURI will not encode following special charcaters

A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

let uri = "?qry=M & L"

console.log(encodeURI(uri))

So you can use encodeURIComponent ,this will encode all the characters except these

A-Z a-z 0-9 - _ . ! ~ * ' ( )

let uri = "?qry=M & L"

console.log(encodeURIComponent(uri))
