如何将某些部分更改为小写且没有空格？

Question

我到此为止已经可以在页面上打印出我想要的信息了（这仅供我个人使用），作为生成器来为我加快速度。但是我想得到一部分以删除表单条目之间的任何空格，并将其更改为小写。例如，当它显示去年的#Korn采访时我希望它改为显示#korninterviewlastyear但仅在生成主题标签的那一部分

非常感谢您提供任何帮助。非常感谢。

其他一切都很好，我想完成的事情

Answer 1

这就是我的做法：

function collect(frm) { 
  document.getElementById("results").innerHTML += "#" + [frm.band.value, frm.song.value].join('').toLowerCase() /* + whatever else you need here... */;
}

您可能还希望摆脱标点符号，因此可以使用String.prototype.replace()函数将任何模式替换为您喜欢的字符串。

另外，我建议使用较新的字符串插值语法切换为连接字符串：

`#${[frm.band.value, frm.song.value].join('').toLowerCase()}`
