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

这是最常见、最可读的方法。

var str = "Test abc test test abc test test test abc test test abc"

方法1:

str = str.replace(/abc/g, "replaced text");

方法2:

str = str.split("abc").join("replaced text");

方法3:

str = str.replace(new RegExp("abc", "g"), "replaced text");

方法4:

while(str.includes("abc")){
   str = str.replace("abc", "replaced text");
}

出口:

console.log(str);
// Test replaced text test test replaced text test test test replaced text test test replaced text

其他回答

我建议通过将其附加到原型链上,为线类添加一个全球方法。

String.prototype.replaceAll = function(fromReplace, toReplace, {ignoreCasing} = {}) { return this.replace(new RegExp(fromReplace, ignoreCasing ? 'ig': 'g'), toReplace);}

它可以用作:

'stringwithpattern'.replaceAll('pattern', 'new-pattern')

与常规表达的i旗案例不敏感

console.log('App started'.replace(/a/g, '')) // Result: "App strted"
console.log('App started'.replace(/a/gi, '')) // Result: "pp strted"

试试这:

String.prototype.replaceAll = function (sfind, sreplace) {
    var str = this;

    while (str.indexOf(sfind) > -1) {
        str = str.replace(sfind, sreplace);
    }

    return str;
};

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

最简单的解决方案 -

let str = "Test abc test test abc test test test abc test test abc"; str = str.split(" "); str = str.filter((ele, key)=> ele!=="abc") str = str.join(" ")

或者只是 -

str = str.split(““)。过滤器(ele,键) => ele!=“abc”).加入(““)
