问题:

Execute javascript if current location contains html in in. I have tried the below but it doesn't work

var winloc = window.location; //for e.g http://mysite.com/home.html
var ishtml = winloc.match(/html/$);
var dothtml = "html";
if(dothtml==ishtml){
//execute javascript here
}

回答1:

var isHTML = "html" === window.location.pathname.split(".").pop().toLowerCase();
if ( isHTML ) {
    //execute javascript here
}

回答2:

var winloc = window.location.pathname; //for e.g http://mysite.com/home.html
var ishtml = /html$/i.test(winloc); //Remove the i if you want to match only html and not HTML
if(ishtml === true){
    //Your JS
}

My suggestion:

if ( window.location.pathname.match( /html$/ ) ) {
    // do it
}

You don't have to declare local variables if the value are only needed once...

回答5:

var re = /.*(\.html)$/i;
var winloc = window.location.href; //for e.g http://mysite.com/home.html
var ishtml = winloc.match(re)[1];
var dothtml = ".html";
if(dothtml==ishtml){
//execute javascript here
 alert("yes")
}
