java - Multiple search from HTML table -

function dosearch() {    var searchtext = document.getelementbyid('searchterm').value;    var targettable = document.getelementbyid('datatable');    var targettablecolcount;     // loop through table rows.    (var rowindex = 0; rowindex < targettable.rows.length; rowindex++) {       var rowdata = '';        // column count header row.       if (rowindex == 0) {          targettablecolcount = targettable.rows.item(rowindex).cells.length;          continue; //do not execute further code header row.       }        // process data rows. (rowindex >= 1)       (var colindex = 0; colindex < targettablecolcount; colindex++) {          rowdata += targettable.rows.item(rowindex).cells.item(colindex).textcontent;       }        // if search term not found in row data hide row, else show.       if (rowdata.indexof(searchtext) == -1)          targettable.rows.item(rowindex).style.display = 'none';       else          targettable.rows.item(rowindex).style.display = 'table-row';    } } 

this code working great searching 1 keyword, want search multiple keywords separated semicolon (;).

first make function dosearch parameter. instead of :

function dosearch() {         var searchtext = document.getelementbyid('searchterm').value; 

put

function dosearch(searchvalue, rows) {...}  

then

var keywords = document.getelementbyid('searchterm').value.split(';'); 

and loop on function dosearch(keyword[index], rowindexes);

to contain keywords

let function dosearch() return array rowindexes match. , pass next call, until keywords finish.

the last result rowindexes match keywords.
