Make jQuery function run only inside a specific div id or class

I have a jQuery function to change the href on a webpage. How do I make this script only run inside the #container div?

$('a[href*="example.com"]').each(function(){
 var index = this.href.indexOf(".com/");
 this.href = this.href.slice(0, index+5)
})

I've tried this,

$('#container').$('a[href*="example.com"]').each(function(){
 var index = this.href.indexOf(".com/");
 this.href = this.href.slice(0, index+5)
})

but it doesn't work. What's wrong with the code above?

Use .find()

$('#container').find('a[href*="example.com"]').each(function(){
    var index = this.href.indexOf(".com/");
    this.href = this.href.slice(0, index+5)
})

Or use descendant selector

$('#container a[href*="example.com"]').each(function(){
    var index = this.href.indexOf(".com/");
    this.href = this.href.slice(0, index+5)
})

You can also try a slightly different version

$('#container').find('a[href*="example.com"]').attr('href', function(idx, href){
    var index = href.indexOf(".com/");
    return href.slice(0, index + 5)
})
