jQuery remove specific input value before submiting

Here is what I have:

<form method="get" action="" name="advsearch">
  <input type="hidden" name="query" value="">
  <div class="formelement-01">
    <select name="product" size="1" onclick="bq()">
      <option value="" selected="selected">Select Brand</option>
      <option value="brand 1">brand 1</option>
      <option value="brand 2">brand 2</option>
    </select>
  </div>
  <div class="formelement-02">
    <select name="cut" size="1" onchange="bq()">
      <option value="" selected="selected">Select Product Type</option>
      <option value="product 1">product 1</option>
      <option value="product 2">product 2</option>
      <option value="product 3">product 3</option>
    </select>
  </div>
  <div class="formelement-03">
    <input onfocus="if (this.value == 'Enter keywords') this.value = '';" value="Enter keywords" type="text" name="keyword" id="key" onChange="bq()">
  </div>
  <div class="formelement-04">
    <input type="image" src="images/submit.gif" value="Submit" name="Submit" id="sbmit">
  </div>
</form>
<script type="text/javascript">
  function bq() {
   document.advsearch.query.value = document.advsearch.cut.value + " "  + document.advsearch.product.value + " "  + document.advsearch.keyword.value;}
</script>

The form works fine, but if I do not replace the value "Enter keywords" with something else, it gets submitted along with the options I choose.

How do I prevent this specific value, "Enter keywords", from submitting? Please note, the form should be able to submit any other value, just not this one.

I hope there is somebody who can help with this.

Thank you in advance. Elena

You can use the placeholder property of input type but remember this placeholder property will not work on IE.

SO use the following code:

<form method="get" action="" name="advsearch" onSubmit="fun()">

add a function on form. Then use the following script.

<script type="text/javascript">
  function fun() {
    var ele = document.getElementById("key");
    if(ele.value == "Enter keywords") {
       ele.value = "";
    } 
    return true;
  }
</script>

Try with placeholder like

<input value="" placeholder="Enter Keywords" type="text" name="keyword" id="key" onChange="bq()">

I guess you need Html placeholder instead of doing old text validations.

<input type="text" name="mytextbox" placeholder="Enter keywords">

See here for examples and demo
