爱站程序员基地As we have discussed that escape(), unescape() and encodeURI(), decodeURI() are used to encode a decodes the data/URI, these functions do not encode some of the special characters like @+-/.*_.
正如我们已经讨论过的那样，使用scape () ， unescape()和encodeURI()，decodeURI()来对数据/ URI进行解码，这些函数不会对某些特殊字符进行编码，例如@ +-/。* _ 。
But, the functions encodeURIComponent() and decodeURIComponent() can do it.
但是， 函数encodeURIComponent()和decodeURIComponent()可以做到这一点。
Functions encodeURIComponent() and decodeURIComponent() are used to encode and decode the URI along with @+-/.*_ characters. These functions encode, decode all special characters.
函数encodeURIComponent()和decodeURIComponent()函数用于对URI和@ +-/。* _字符进行编码和解码。 这些功能对所有特殊字符进行编码，解码。
Example:
例：
<html><head><title>JavaScipt Example</title></head><body><script>var uri =\"test page.aspx?val=Hello world!!\";//using encodeURI() and decodeURI() functionsvar enc_str = encodeURI(uri);var dec_str = decodeURI(uri);//printing the valuesdocument.write(\"<b>Using encodeURI() and decodeURI()...</b><br>\");document.write(\"Actual URI: \" + uri);document.write(\"<br>\");document.write(\"Encoded URI: \" + enc_str);document.write(\"<br>\");document.write(\"Decoded URI: \" + dec_str);document.write(\"<br><br>\");//using encodeURIComponent() and decodeURIComponent() functionsvar enc_str = encodeURIComponent(uri);var dec_str = decodeURIComponent(uri);//printing the valuesdocument.write(\"<b>Using encodeURIComponent() and decodeURIComponent()...</b><br>\");document.write(\"Actual URI: \" + uri);document.write(\"<br>\");document.write(\"Encoded URI: \" + enc_str);document.write(\"<br>\");document.write(\"Decoded URI: \" + dec_str);document.write(\"<br>\");</script></body></html>
