decodeURI decodes space as + symbol
提问by user2435840
I have created a Google Custom Search. The logic is when a user search, the page will display result and the title of the page will be changed to the search term using javascript. I use decodeURI to decode the unicode characters. But the space is decode as +. For example if I search money making it will be decoded as money+making and it is displayed as title. Someone please help to solve this. I want to display space instead of the symbol +.

The Google Closure Libraryprovides its own urlDecode function for just this reason. You can either use the library or below is the open source solutionfor how they solve it.
正是出于这个原因，Google Closure Library提供了自己的 urlDecode 函数。您可以使用该库或以下是他们如何解决它的开源解决方案。
/**
* URL-decodes the string. We need to specially handle '+'s because
* the javascript library doesn't convert them to spaces.
* @param {string} str The string to url decode.
* @return {string} The decoded {@code str}.
*/
goog.string.urlDecode = function(str) {
return decodeURIComponent(str.replace(/\+/g, ' '));
};

You can use replace function for this:
您可以为此使用替换功能：
decodeURI(query).replace( /\+/g, ' ' )
