如何在Javascript中使用.replace？

Question

I have some Javascript I am using on my site that automatically generates breadcrumbs based on my file structor. The problem I am having is that the names it displays are based on the file names, and some times those names have under scores in them. here is an example:

Home / Marketing / News_events / News & Events Home Page

What I would like to do is remove the under score in News_events and replace it with a space... same with all the bread crumbs on the site.

My Java Script is not very good but I think I have to add something like this:

 string.replace(/_/g,' '); 

I'm just not sure where or how to place it with in the Javascript.

Here is the full Javascript:

 function breadcrumbs(){ sURL = new String; bits = new Object; var x = 0; var stop = 0; var output = '<a href="/"><i class="fa fa-home fa-lg"></i></a> &nbsp;/&nbsp; '; sURL = location.href; sURL = sURL.slice(8,sURL.length); chunkStart = sURL.indexOf("/"); sURL = sURL.slice(chunkStart+1,sURL.length) while(!stop){ chunkStart = sURL.indexOf("/"); if (chunkStart != -1){ bits[x] = sURL.slice(0,chunkStart) sURL = sURL.slice(chunkStart+1,sURL.length); }else{ stop = 1; } x++; } for(var i in bits){ output += "<a href=\\""; for(y=1;y<xi;y++){ output += "../"; } output += bits[i] + "/\\">" + bits[i] + "</a> &nbsp;/&nbsp; "; } document.write(output + document.title); } 

Any help would be greatly appreciated!

You just need to replace this line, so that bits[i] has the underscores replaced:

output += bits[i] + "/\\">" + bits[i] + "</a> &nbsp;/&nbsp; ";

Turns into:

output += bits[i] + "/\\">" + bits[i].replace(/_/g,' ') + "</a> &nbsp;/&nbsp; ";
