check the value of a textbox that whether it contains a particular set of strings or not

I want to check the value of a textbox that whether it contains a particular set of strings or not. How do I do this? (preferably using jquery)

I have a textbox where a user enters something. I want to check whether the string he enters contains BOTH "@" and "port". Please help..

I tried using contains but it is giving false positives.

Here is the code I used.

if($("#id:contains('@'):contains('port')")) {
    $("#1st").hide();
    $("#2nd").show();
} else {
    alert("Wrong value entered.");
}

Here is basic solution with other example which is very simple and won't need any other file to be imported.

function check()

{

    var val = frm1.uname.value;
    //alert(val);
    if (val.indexOf("@") > 0)
    {
        alert ("email");
        document.getElementById('isEmail1').value = true;
    }else {
        alert("usernam");
          document.getElementById('isEmail1').value = false;
    }
}

Try a combination of javascript and jQuery

var txtVal = $("#id").attr('value');
if(txtVal.indexOf("@")!= -1 && txtVal.indexOf("port")!= -1)
   alert('yes');
else
   alert('no');

Use $('#id').val() to get the value. Then you can use regular JavaScript functions to check if it contains certain values.

var value = $('#id').val();
if(~value.indexOf('@') && ~value.indexOf('port')) {
    $("#1st").hide();
    $("#2nd").show();
} else {
    alert("Wrong value entered.");
}

In case you wonder what the ~ does: it's a smart way to check for != -1 as ~-1 == 0.
