Hello,
I have a javascript code helping me to dynamically create row after row in a table and to delete a row from that table. each row has four cells. cell 1 for instance contains a text zone. to differentiate cell1 from row 1 with cell1 from row 2, I rename my cell 1 like that cell1.name= cell1.name + '_' + row.rowIndex.
I create a submit button so that I could read data entered by a user in the rows of the table and I try to print $_GET. but there is nothing inside. How could I access to my DOM objects in PHP?
I am grateful for your help.
my HTML + PHP code
<body >
<?php
if (isset($_GET['Enter'])){
print_r($_GET);
}
?>
<h1> Create an Item </h1>
<form method="GET" action="func.html">
<table align="center" border = "2" cellspacing ="0" cellpadding="3" id="table">
<tr><td><b>Functionality Name:</b></td> <td><b>Description:</b></td> <td><b>Status:</b></td> <td><input type="button" Name= "Ajouter" Value="Ajouter" onclick="go()"></td></tr>
</table>
<input type="submit" name="submit" value="Enter">
</form>
</body>
and my Javascript code:
<script>
function getXhr(){
var xhr = null;
if(window.XMLHttpRequest) // Firefox and others
xhr = new XMLHttpRequest();
else if(window.ActiveXObject){ // Internet Explorer
try {
xhr = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
xhr = new ActiveXObject("Microsoft.XMLHTTP");
}
}
else { // XMLHttpRequest not supported by your browser
alert(" Your browser does not support XMLHTTPRequest objects...");
xhr = false;
}
return xhr
}
/**
* method called when the user clicks on the button
*/
function go(){
var xhr = getXhr()
// We defined what we gonna do with the response
xhr.onreadystatechange = function(){
// We do somthing once the server's response is OK
if(xhr.readyState == 4 && xhr.status == 200){
var body = document.getElementsByTagName("body")[0];
// Retrieve <table> ID and create a <tbody> element
var tbl = document.getElementById("table");
var tblBody = document.createElement("tbody");
var row = document.createElement("tr");
var cell_1 = document.createElement("td");
var cell_2 = document.createElement("td");
var cell_3 = document.createElement("td");
var cell_4 = document.createElement("td");
// Create the first cell which is a text zone
var cell1=document.createElement("input");
cell1.type="text";
cell1.name="fname";
cell1.size="20";
cell1.maxlength="50";
cell_1.appendChild(cell1);
// Create the second cell which is a text area
var cell2=document.createElement("textarea");
cell2.name="fdescription";
cell2.rows="2";
cell2.cols="30";
cell_2.appendChild(cell2);
// Create the second cell which is a combo box
var cell3 = document.createElement("div");
cell3.id="rs";
cell3.innerHTML=xhr.responseText;
cell_3.appendChild(cell3);
// Create the fourth cell which is a button
var cell4=document.createElement("input");
cell4.type="button";
cell4.value="Delete"
cell4.onclick=delRow;
cell_4.appendChild(cell4);
// add cells to the row
row.appendChild(cell_1);
row.appendChild(cell_2);
row.appendChild(cell_3);
row.appendChild(cell_4);
// add the row to the end of the table body
tblBody.appendChild(row);
// put the <tbody> in the <table>
tbl.appendChild(tblBody);
// Rename cells with the row index
var ind=row.rowIndex;
var liste_fname = row.getElementsByTagName("input");
for(i=0; i < liste_fname.length; i++)
{
if(liste_fname[i].name == "fname")
{
liste_fname[i].name = liste_fname[i].name + "_" + ind; //give fname_1, fname_2, fname_3, ...
}
}
var fd = row.getElementsByTagName("textarea");
fd[0].name = fd[0].name + "_" + ind;
var cd = row.getElementsByTagName("div");
cd[0].id = cd[0].id + "_" + ind;
var selectname = row.getElementsByTagName("select");
selectname[0].name = selectname[0].name + "_" + ind;
// appends <table> into <body>
body.appendChild(tbl);
// sets the border attribute of tbl to 1;
tbl.setAttribute("border", "1");
}
}
xhr.open("GET","fstatus.php",true);
xhr.send(null);
}
function delRow(){
var i= this.parentNode.parentNode.rowIndex;
document.getElementById('table').deleteRow(i);
}
</script>
Best regards,
