Dynamically Filter Rows Of A HTML Table Using JavaScript

Post a Comment
So I have this table:
Broj_pu Naziv_pu ID

Solution 1:

This question is reminding me of how java script is nasty without any framework support :)

However I have sorted-out this issue for you ( tested on firefox 10.0.2).

check the complete working solution on jsfiddle

please remember this is just working example , you might need to write ALL-Browser compliant script .

script:

var filters=['hide_broj_pu','hide_naziv_pu','hide_ID','hide_naselje','hide_zupanija'];

function ExcludeRows(cls){

  var skipRows=[];

  for(i=0;i<filters.length;i++)
      if(filters[i]!=cls) skipRows.push(filters[i]);

  var pattern=skipRows.join('|')

  return pattern;
}

function Filter(srcField){

   var node=srcField.parentNode;

   var index=srcField.parentNode.cellIndex;
    //all the DATA rows

   var dataRows= document.getElementsByClassName("row");

   //ensure that dataRows do not have any filter class added already
   var kids= dataRows.length;

   var filter ='hide_'+srcField.id;

   var pattern = ExcludeRows(filter);

   var skipRow = new RegExp(pattern,"gi");

   var searchReg =new RegExp('^'+srcField.value,'gi');

   var replaceCls= new RegExp(filter,'gi');

   for(i=0; i< kids ; i++){
       //skip if already filter applied  

       if(dataRows[i].className.match(skipRow)) continue;

       //now we know which column to search
       //remove current filter
       dataRows[i].className=dataRows[i].className.replace(replaceCls,'');

       if(!dataRows[i].cells[index].innerHTML.trim().match(searchReg))
          dataRows[i].className=dataRows[i].className +' '+ filter;

    }



}

HTML

<table border="1" align="center">
<tr><td>Broj_pu</td><td>Naziv_pu</td><td>ID</td><td>Naselje</td><td>zupanija</td></tr>
<tr>
<td><input type="text" ID="broj_pu"    onkeydown="Filter(this)" /></td>
<td><input type="text" ID="naziv_pu"   onkeydown="Filter(this)" /></td>
<td><input type="text" ID="ID"         onkeydown="Filter(this)" /></td>  
<td><input type="text" ID="naselje"    onkeydown="Filter(this)" /></td>
<td><input type="text" ID="zupanija"   onkeydown="Filter(this)" /></td>   
</tr>

<tr class="row" ><td>10000</td><td>Zagreb</td><td>1</td><td>Sljeme</td><td>ZAGREBACKA</td></tr>
<tr class="row" ><td>10000</td><td>Zagreb</td><td>2</td><td>Zagreb-dio</td><td>ZAGREBACKA</td></tr>
</table>

CSS

.hide_broj_pu,
.hide_naziv_pu,
.hide_ID,
.hide_naselje,
.hide_zupanija
{display:none}

Solution 2:

For Javascript Table Search, Try:

<p>Search: <input type="text" id="searchTerm" onkeyup="doSearch()" /></p>

<table id="dataTable">

<script>
function doSearch() {
            var input, filter, found, table, tr, td, i, j;
            input = document.getElementById("searchTerm");
            filter = input.value.toUpperCase();
            table = document.getElementById("dataTable");
            tr = table.getElementsByTagName("tr");
            for (i = 0; i < tr.length; i++) {
                td = tr[i].getElementsByTagName("td");
                for (j = 0; j < td.length; j++) {
                    if (td[j].innerHTML.toUpperCase().indexOf(filter) > -1) {
                        found = true;
                    }
                }
                if (found) {
                    tr[i].style.display = "";
                    found = false;
                } else {
                    tr[i].style.display = "none";
                }
            }
        }
    </script>
