jq简单封装replaceAll

(function ($) {
    $.fn.extend({
        nFCReplaceAll:function(str,reallyDo, replaceWith){
            return str.nReplaceAll(reallyDo, replaceWith);
        }
    });
})
// 替换所有
String.prototype.nReplaceAll = function(reallyDo, replaceWith, ignoreCase) {
    if (!RegExp.prototype.isPrototypeOf(reallyDo)) {
        return this.replace(new RegExp(reallyDo, (ignoreCase ? "gi" : "g")), replaceWith);
    } else {
        return this.replace(reallyDo, replaceWith);
    }
};

var tempStr = '大家好，我想换行';

tempStr = tempStr .nReplaceAll('，','</br>，');// 调用方式1
