    Function Array of Names

    If I had the following code:

    Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <title>4.9</title>
    </head>
    
    <body>
    <script type="text/javascript">
    function e_names(my_names){
    //create array list of names, return number of names in array than end in either
    //ie or y
    
    var my_array_names=new Array("Ryan Butler", "Pat Lonie", "Michell Lay");
    }
    
    </script>
    
    </body>
    </html>
    I'm trying to find a way to call and check to see whether the array of names contains an "ie" or "y" which it will since I created my array to have those. I'm guessing that maybe I'll be using argument.length to check the number?? I'm thinking it needs to be a regular expression to check which ones end in "ie" or "y."

    If anyone could shed some light somewhere it would be great.

    Loop through the array and then check each entry using a regular expression.

    So something like this?


    Code:
    <html>
    <head>
    
    </head>
    <body>
    function e_names(my_names){
    //create array list of names, return number of names in array than end in either
    //ie or y
    
    //create an empty variable to determine how many names end in requirements
    var count=[];
    
    //create a for loop to loop through my array set
    for(var i=0; i < my_array.length; i ++){
        if(count[my_array[i]]){
          count[my_array[i]]+=1;
        }
      }
    }
    
    </script>
    
    <script type="text/javascript">
    
    //create new array variable to hold various values to test for
    var my_array = new Array("Butler", "Lonie", "Lay");
    //create result variable and set equal to my function call and pass parameter
    var result=e_names(my_array);
    
    //display the message in the browser
    document.writeln("The number of names that end in either ie or y are " + result);
    </script>
    </body>
    </html>
    Except perhaps replacing count with a regular expression?

    Kind of.
    Here is a sample:
    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Untitled Document</title>
    <script>
    
    var NameArray =new Array("Ryan Butler", "Pat Lonie", "Michell Lay");
    
    
    for (var i in NameArray)
    {
    	var name = NameArray[i];
    	if (name.search(/ie/) != -1)
    	{
    		alert(name +  " contains ie")
    	}
    	if (name.search(/y/) != -1)
    	{
    		alert(name +  " has a y")
    	}
    }
    
    
    </script>
    </head>
    
    <body>
    </body>
    </html>

    Or using for loops and ignoring case:
    PHP Code:
    var NameArray = ["Ryan Butler""Pat Lonie""Michell Lay"];
    for (var 
    NameArray.length-1>= 0i--) {
       var 
    name NameArray[i];
       if (/
    ie/i.test(name)) {
          
    alert(name " contains ie");
       }
       if (/
    y/.test(name)) {
          
    alert(name " contains y");
       }

    OR for multiple ones:
    PHP Code:
    var NameArray = ["Ryan Butler""Pat Lonie""Michell Lay"];
    var 
    checks = [/ie/i,/y/i];
    for (var 
    NameArray.length-1>= 0i--) {
       var 
    name NameArray[i];
       for (var 
    checks.length-1>= 0j--) {
       if (
    checks[i].test(name)) {
          
    alert(name " contains "+checks[i].replace(/\//g,"");
       
    }
      }

    Edit has expired on the previous post, so I better so what I meant. There is a back slash missing:
    PHP Code:
    alert(name " contains "+checks[i].replace(/BACKSLASH//g,"");

    Thanks everyone. I was able to adjust my script to return a value after about an hour of work. I'm reminding myself how pesky JS can be.

    following code lets u enter the names into an array and then check what it ends with

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Untitled Document</title>
    <script>

    var NameArray =new Array("Ryan Butler", "Pat Lonie", "Michell Lay");
    var new_name,index,last;

    while (new_name= prompt("pls type a new name"," "))
    {
    last= NameArray.length-1;
    while(last>=0&&NameArray[last]>new_name)
    {
    NameArray[last+1]=NameArray[last];
    last--;
    }
    NameArray[last+1]=new_name;
    document.write("<p><b>the new name list is:<b>","<br />");
    for (index=0;index<NameArray.length;index++)
    document.write(NameArray[index], "<br />");
    document.write("<p>");
    }

    for (var i in NameArray)
    {
    var name = NameArray[i];
    if (name.search(/ie/) != -1)
    {
    alert(name + " contains ie")
    }
    if (name.search(/y/) != -1)
    {
    alert(name + " has a y")
    }
    }

    Well for what its worth, this is how I did it.

    HTML Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <title>4.9</title>
    </head>
    
    <body>
    <script type="text/javascript">
    //create array list of names, return number of names in array than end in either
    //ie or y
    var my_array_names=new Array("Ryan Butler", "Pat Lonie", "Michell Lay");
    var count = 0;
    while(my_array_names.length){
    	var tmp = my_array_names.shift();
    	tmp = tmp.toLowerCase().slice(-2);
    	if( tmp=="ie" || tmp.slice(-1)=="y" ) count++;
    }
    console.log("You have an array with : "+ count +" names that either have 'ie' or a 'y' at the end.")
    
    
    
    </script>
    
    </body>
    </html>
    You can replace the console.log for an alert if you prefer. Don't see why you needed a function with the array in it so I got rid.
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
