根據一條線:

s = "Test abc test test abc test test test abc test test abc";

这似乎只是在上面的行中删除ABC的第一次出现:

s = s.replace('abc', '');

如何替代所有事件?


当前回答

可替代的独特价值

String.prototype.replaceAll = function(search_array, replacement_array) { // var target = this; // search_array.forEach(function(substr, index) { if (typeof replacement_array[index]!= "undefined") { target = target.replace(new RegExp(substr, 'g'), replacement_array[index] ) }); // return target; }; // Use: var replacedString = "This topic commented o

其他回答

使用常规表达式:

str.replace(/abc/g, '');

以下功能为我工作:

String.prototype.replaceAllOccurence = function(str1, str2, ignore)
{
    return this.replace(new RegExp(str1.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g,"\\$&"),(ignore?"gi":"g")),(typeof(str2)=="string")?str2.replace(/\$/g,"$$$$"):str2);
} ;

现在,请称这些功能如下:

"you could be a Project Manager someday, if you work like this.".replaceAllOccurence ("you", "I");

简单地复制并将此代码插入您的浏览器控制台进行测试。

添加 /g

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

// Replace 'hello' string with /hello/g regular expression.
document.body.innerHTML = document.body.innerHTML.replace(/hello/g, 'hi');

G 意味着全球性

你可以尝试这样:

示例数据:

var text = "heloo,hai,hei"

text = text.replace(/[,]+/g, '')

text.forEach((value) => {
  hasil = hasil.replace(',', '')
})
var str = "ff ff f f a de def";
str = str.replace(/f/g,'');
alert(str);
