I have mention code and also dynamic code for textbox with js. i am facing problem in chrome while running this code but this same code is running on firefox properly, so please give me some suggestion regarding this code.
html code for textbox
<td><input class="form-control" required type='text' id='productname_1' name='productname[]'/></td> <td><input class="form-control" readonly="" required type='text' id='price_1' name='price[]'/></td> <td><input class="form-control" required type='text' id='quantity_1' name='quantity[]'/></td> <td><input class="form-control" readonly="" required type='text' id='total_1' name='total[]'/> </td>
Dymamic html code for textbox
<td><input class='form-control productname12_"+i+"' required type='text' id='productname_"+i+"' name='productname[]'onchange='myFunction()'/></td> <td><input class='form-control' readonly type='text' id='price_"+i+"' required name='price[]'/></td><td><input class='form-control' type='text' required id='quantity_"+i+"' name='quantity[]'/></td><td><input class='form-control' readonly type='text' required id='total_"+i+"' name='total[]'/></td>
js code
function myFunction() { var x = document.getElementById('productname_'+j).value; //alert(x); $.ajax({ type:"POST", url:"addplaceorder/getproductprice", data:{'name':x}, cache:false, success:function(html){ //alert(html); //alert('#price_'+k); $('#price_'+k).val(html); } }); $('#quantity_'+j).change(function(){ var val = $(this).val(); var price = $('#price_'+k).val(); //alert(name); var total = (val* price); //alert(total); totalamount = totalamount+total; //alert(totalamount); $('#total_'+k).val(total); $('#showtotal').text(totalamount); }); $('#quantity_'+j).keypress(function (e) { if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) { //display error message //$("#errmsg").html("Digits Only").show().fadeOut("slow"); return false; } }); j++;k++; }
This might be the problem
var x = document.getElementById('productname_'+j).value;
The variable j is not initialized, therefore the value is undefined. I suppose that there is not element with id "productname_undefined". So when you try to read value from that undefined element, you will get an error. Something like "can not read property value of undefined"
PS: It is better to use the debugger
statements, rather then alert()
