给定一个这样的字符串:
"The dog has a long tail, and it is RED!"
什么样的jQuery或JavaScript魔法可以用来保持空间只有一个最大空间?
目标:
"The dog has a long tail, and it is RED!"

使用nodepad++函数,下面的regex对我来说很好,
发现:{1}\ \ s + K 替换:留空

更健壮的:
function trim(word) { word = word.replace(/[^\x21-\x7E]+/g, ' '); // change non-printing chars to spaces return word.replace(/^\s+|\s+$/g, ''); // remove leading/trailing spaces }
let nameCorrection = function (str) {
let strPerfect = str.replace(/\s+/g, " ").trim();
let strSmall = strPerfect.toLowerCase();
let arrSmall = strSmall.split(" ");
let arrCapital = [];
for (let x of arrSmall.values()) {
arrCapital.push(x[0].toUpperCase() + x.slice(1));
}
let result = arrCapital.join(" ");
console.log(result);
};
nameCorrection("Pradeep kumar dHital");

var str = "The dog has a long tail, and it is RED!";
str = str.replace(/ {2,}/g,' ');
编辑: 如果你想替换所有类型的空白字符,最有效的方法是这样的:
str = str.replace(/\s{2,}/g,' ');
我们可以在sed system命令的帮助下使用下面的正则表达式。类似的正则表达式可用于其他语言和平台。
将文本添加到某个文件中,例如test
manjeet-laptop:Desktop manjeet$ cat test
"The dog has a long tail, and it is RED!"
我们可以使用下面的正则表达式将所有空格替换为单个空格
manjeet-laptop:Desktop manjeet$ sed 's/ \{1,\}/ /g' test
"The dog has a long tail, and it is RED!"
希望这能起到作用
