  • 0

I’m trying to use jQuery to add dynamic Add/Remove row function, but I meet some question in IE8, its clone() object cannot modify element name and cannot use javascript form (prhIndexed[i].prhSrc).functionKey.

In FireFox it works very well, source code as attachment, please do me a favor and help me to solve the problem.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function() {

var _table = jQuery("#prh");    
var _tableBody = jQuery("tbody",_table);    

var _addRowBtn = jQuery("#controls #addRow");

var _addRowsNumber= jQuery("#controls #add_rows_number");   

var blankRowID = "blankRow";

_addRowBtn.click(function(){                
    var newRow = jQuery("#"+blankRowID).clone(true)
                    .appendTo(_tableBody)
                    .attr("style", "display: ''")
                    .addClass("rowData")                                                    
                    .removeAttr("id");                  
     }
         refreshTable(_table);          
}
return false; 
});

function refreshTable(_table){

    var tableId = _table.attr('id');        
    var count =1; // ignore hidden column


    jQuery ( "#"+tableId ).find(".rowData").each(function(){

        jQuery(this).attr('id', tableId + "_" + count );//// update tr rowid
        count ++;           
    });     

    count =0;       
    jQuery ( "#"+tableId ).find("input[type='checkbox'][name^='"+tableId+"']").not(".checkBoxAll").each(function(){

        jQuery(this).attr('id', tableId + "_ckbox" + count );
        jQuery(this).attr('name', tableId + "_" + count ); // IE8 cannot modify name ??

        count ++;           
    });
 };  
});
</script>

    In last weet,I was redraw my table, the problem finised !!

            // update tr rowid
    jQuery ( "#"+tableId ).find(".rowData").each(function(){

        var rowHtml="<tr id='prh_"+count+"'class='refreshData'>"; // another class          

        var myRow = jQuery(this);

        jQuery('td', myRow).each(function(){
            rowHtml += "<td>";  

            var myTd = jQuery(this);

            jQuery ( myTd ).find("input[type='checkbox']").each(function(){

                var oldCkbox = jQuery(this);
                var ckboxName = oldCkbox.attr('name', 'prh_'+ count ).attr('name');

                var newCkbox = jQuery('<input type=checkbox name="' + ckboxName + '">');                    
                .....               

                jQuery(oldCkbox).replaceWith(newCkbox);


            });


            rowHtml += myTd.html();
            rowHtml += "</td>";
        });

        rowHtml += "</tr>";
        // empty to clean clone event
        jQuery(myRow).empty().addClass("rowData").removeClass("refreshData").html(rowHtml);

        count ++;           
    });
