control radio button from textfield value

everyone..i want after i type "0203-ED" in textfield ...two character behind that text can control the radio button.. "ED" character from that text can make one radiobutton which has value="ED" are checked...

this is my code:

<script type="text/javascript">
      var model=$("#tags1").val();
      var version[0,0]="JD";
      var version[0,1]="87.5-107.9";
      var version[1,0]="ED";
      var version[1,1]="87.5-108.0";
      var versi开发者_如何学运维on[2,0]="EED";
      var version[2,1]="65.0-74.0";

     // each version
      for (var i = 0; i < version.length; i ++) {
          if (model.lastIndexOf(version[i,0])!=-1) {
              $("#value").replaceWith("<div id='value'>"+version[i,1]+"</div>");
          } else {
                $("#value").replaceWith("<div id='value'></div>")
          }
      // end each
      }
  </script>

what's wrong with my code??

I see a couple things going on.

First, why do you have a default: in there? That's a keyword used in switch statements; it's not valid in an if statement. Remove it entirely.

You also have model,lastIndexOf instead of model.lastIndexOf

you don't have to use .replaceWith()...

 for (var i = 0; i < version.length; i ++) {
      if (model.lastIndexOf(version[i,0])!=-1) {
          $("#value").html(version[i,1]);
      } else {
       //default
          $("#value").html("");
      }
  // end each
  }

Watch your language typing. It should be text/javascript. Right now you have text/jaavascript. Depending on the browser and your doctype, this could prevent your script from even executing (it wouldn't just fail silently, it wouldn't even get the chance to fail).

In addition to the answers already given, try declaring your array only once. There are several ways create the data structure you're after. Use whichever style you find most comfortable.

var version = [['JD',"87.5-107.9"],["ED","87.5-108.0"],["EED","65.0-74.0"]];

var version = [];
version[0] = ["JD","87.5-107.9"]
version[1] = ["ED","87.5-108.0"];
version[2] = ["EED","65.0-74.0"];

var version = [];
version[0] = [];
version[0,0]="JD";
version[0,1]="87.5-107.9";
version[1] = [];
version[1,0]="ED";
version[1,1]="87.5-108.0";
version[2] = [];
version[2,0]="EED";
version[2,1]="65.0-74.0";

About the third version, though, I'm actually not sure that your array notation (version[0,1]) is universally supported. I don't think I've seen anyone use that notation in more than 10 years. Typically, you access members of a multi-dimensional array with the notation: myArray[x][y]. But maybe that's just a style difference. I'm not sure.

[EDIT] Are you trying to do something like this? This isn't terribly efficient, but it may be a starting point for you. In this case, jQuery is definitely your friend.

<input type="radio" name="version" value="87.5-107.9" /><label class="version">JD</label><br />

<input type="radio" name="version" value="65.0-74.0" /><label class="version">EED</label><br />
<input type="text" name="version_text" value="Enter your value" />

    var rxLabelValue;
    var isValueFound = false;
    rxLabelValue = new RegExp( $(jVersionTextInput).val() );
    for (var i = 0; i < intVersionCount; i++) {
        if (!isValueFound && rxLabelValue.test($(jLabels[i]).html())) {
            jRadioButtons[i].checked = true;
            isValueFound = true;
        }
