change javascript variable based on php...

[Dragen]

Hi,

not sure if this should be in javascript or php...

I've got a script which allows someone to insert an extra text input into a form:

var arrInput = new Array(0);
var arrInputValue = new Array(0);

function addInput() {
  if (arrInput.length < 1) {
  arrInput.push(arrInput.length);
  arrInputValue.push("");
  }
  display();
}

function display() {
  document.getElementById('parah').innerHTML="";
  for (intI=0;intI<arrInput.length;intI++) {
    document.getElementById('parah').innerHTML+=createInput(arrInput[intI], arrInputValue[intI]);
  }
}

function saveValue(intId,strValue) {
  arrInputValue[intId]=strValue;
}  

function createInput(id,value) {
  return "<input type='text' name='"+ id +"_name' onchange='javascript:saveValue("+ id +",this.value)' value='"+ value +"'><br />";
}

function deleteInput() {
  if (arrInput.length > 0) { 
     arrInput.pop(); 
     arrInputValue.pop();
  }
  display(); 
}

above I've got the function:

function createInput(id,value) {
  return "<input type='text' name='"+ id +"_name' onchange='javascript:saveValue("+ id +",this.value)' value='"+ value +"'><br />";
}

Now what I'm trying to do is change the name certain value.

 

I've got a php script which gets data from a database to create a list of inputs:

<?php
$sql = "SELECT * FROM committee WHERE position = 'comm' ORDER BY id ASC";
if ($result = mysql_query($sql)) {
	if (mysql_num_rows($result)) {
		 while ($row = mysql_fetch_assoc($result)) {
			echo " <input type=\"text\" name=\"".$row['id']."_name\" value=\"".$row['name']."\" size=\"15\" />,"; // creates input
		}
  		} else {
   			echo "Sorry, but no results were found found\n";
    		}
	} else {
  		echo "Query failed<br />\n$sql<br />\n".mysql_error()."\n";
  	}
?>

 

basically I need to get the id variable to start at one higher than the last php $row['id'].. I'm not sure that it's possible though.

you can build the javascript dynamically with php so that the php creates the value that gets downloaded by the browser but if this does not suit your needs then you should look into ajax and json.

do you mean having the whole javascript function in a php echo?
