How Can Variable And That Value Move Freely In The Cycle Of Php->html->js->php

I am adding the comments input box of every XML-RSS article. When I select a RSS url, that results are commonly as below PHP code for ($i=0; $i<=19; $i++) { $item_title=$x-&g

Solution 1:

I have tried so many times. At last I got the good result for going to the better. PHP code is

 echo " <option  id=".$i." onclick=\"showComment".$i."(this.value)\" value=".$item_link4."> Show Comments </option>";  

And I changed JS code as below.

<script>functionshowComment0(str) {
if (str.length == 0) { 
    document.getElementById("0").innerHTML = "";
    return;
 } else {
    var xmlhttp = newXMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("0").innerHTML = this.responseText;
        }
    };

     var q = document.getElementById("0").value;
    xmlhttp.open("GET", "showComment.php?q=" +q, true);
    xmlhttp.send();
 }
}
</script>
    ....

  <script>functionshowComment22(str) {
if (str.length == 0) { 
    document.getElementById("22").innerHTML = "";
    return;
 } else {
    var xmlhttp = newXMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("22").innerHTML = this.responseText;
        }
    };

     var q = document.getElementById("22").value;
    xmlhttp.open("GET", "showComment.php?q=" +q, true);
    xmlhttp.send();
 }
}
</script><script>functionshowComment23(str) {
if (str.length == 0) { 
    document.getElementById("23").innerHTML = "";
    return;
 } else {
    var xmlhttp = newXMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("23").innerHTML = this.responseText;
        }
    };

     var q = document.getElementById("23").value;
    xmlhttp.open("GET", "showComment.php?q=" +q, true);
    xmlhttp.send();
 }
}
</script>

So I made Id 0 to 18 script. That is, 19 scripts are necessary. I am waiting for better answer.
