Replace underscores in string
提问by blasteralfred Ψ
I have a string var string = "my__st_ri_ng". I want to replace all underscores with single space and I want to store it it another variable. Each underscore should have a space replacement, which means multiple consecutive underscores should have respective number of empty spaces. I want to get my mentioned variable as my<sp><sp>st<sp>ri<sp>ng. How can I do this using jquery??
我有一个字符串var string = "my__st_ri_ng"。我想用单个空格替换所有下划线，我想将它存储为另一个变量。每个下划线都应该有一个空格替换，这意味着多个连续的下划线应该有各自的空格数。我想将我提到的变量作为my<sp><sp>st<sp>ri<sp>ng. 我如何使用 jquery 做到这一点？
Thanks in advance...:)
提前致谢...:)

What you need is Javascript's replacefunction.
你需要的是Javascript的replace功能。
var str1 = "my__st_ri_ng";
var str2 = str1.replace(/_/g, ' ');
You do not need jQuery at all for this task...
你根本不需要jQuery来完成这个任务......

To replace all occurrences of _, use a regular expression with the g(global) flag.
要替换所有出现的_，请使用带有g（全局）标志的正则表达式。
"my__st_ri_ng".replace(/_/g, " "); // "my st ri ng"

You don't need jQuery or even RegEx, just simple JavaSript:
你不需要 jQuery 甚至 RegEx，只需要简单的 JavaSript：
