you have to use the RegExp with global option offered by lodash.

你必须使用 lodash 提供的带有全局选项的 RegExp。

so just use

所以只需使用

var text = "azertyazerty";
_.replace(text,new RegExp("az","g"),"qu")

to return quertyquerty

返回 quertyquerty

I love lodash, but this is probably one of the few things that is easier without it.

我喜欢 lodash，但这可能是少数没有它更容易的事情之一。

var str = str.split(searchStr).join(replaceStr)

As a utility function with some error checking:

作为带有一些错误检查的实用函数：

var replaceAll = function (str, search, replacement) {
  var newStr = ''
  if (_.isString(str)) { // maybe add a lodash test? Will not handle numbers now.
    newStr = str.split(search).join(replacement)
  }
  return newStr
}

For completeness, if you do really really want to use lodash, then to actually replace the text, assign the result to the variable.

为了完整起见，如果您真的真的想使用 lodash，那么要实际替换文本，请将结果分配给变量。

var text = 'find me find me find me'
text = _.replace(text,new RegExp('find','g'),'replace')
