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.
Ben tablonun satırları bir kullanıcı tarafından girilen verileri okuyabilir ki ben bir gönderme düğmesi oluşturmak ve ben $ _GET yazdırmayı deneyin. ama içinde bir şey yok. PHP nasıl benim DOM nesnelerine erişebilir?
Ben yardım için minnettarım.
Benim HTML + PHP kodu
<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>
ve benim Javascript kodu:
<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

var body = document.getElementsByTagName("body")[0];

// 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);

// 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);
}
