match is not a function

[lcborn4]

item[column.name].match is not a function

Has anybody gotten this error before?

return item[column.name].match(column.filtering.filterString);

is .match are javascript function?

So im not sure why match function wasn't found but i found a workaround by using ==

return (item[column.name] === column.filtering.filterString);

string.match() is javascript function.
parameter is regex.

you will get that error, when null.match. so You need to convert all undefined or null to ''(emptyString).

Additionally regex syntax will now allow |\/[](). You need to make new function for this case.

Can I know the function??

I am trying to fix by adding if conditionif (column.filtering) { filteredData = filteredData.filter((item:any) => { if(item[column.name] === null){ item[column.name] = ""; } return item[column.name].match(column.filtering.filterString); }); } but it's not working. Can someone post the solution??

With this return (item[column.name] === column.filtering.filterString); search is not working

another if helped me:

if (item[column.name]){
            if (item[column.name].toString().match(this.config.filtering.filterString)) {
            flag = true;
            }
        }

data shouldn't contain nullstring. This is the first case.

Before drawing table you need to convert null to ''(empty string).
Second is regex.

convertSpecialCharacter(str:string):string {
    const regex = /\/|\\|\(|\)|\[|\]|\|/g;
    let m;
    while ((m = regex.exec(str)) !== null) {
      if (m.index === regex.lastIndex) {
        regex.lastIndex++;
      }
      str = str.substr(0, m.index) + '\\' + str.substr(m.index);
      regex.lastIndex++;
    }
    return str;
  }

return item[column.name].toLowerCase().match(this.publicService.convertSpecialCharacter(column.filtering.filterString).toLowerCase());

I have the same error, but don't know why. filterString is not undefined, it's an empty string but item[column.name] is an integer, maybe it's the problem
