Finding if a value has a value - Does Image SRC contain a "1"?

I am trying to figure out how to check if a value has a value. Like if an image src has a "1" in its value. Kind of like below even though this one doesn't work:


if(document.getElementById("MyID").src contains "1"){
DO THIS...
}
else{
Do THAT...
}


Any comments or suggestions are greatly apreciated. Thanks.
