javascript - After calling function I'm getting error saying undefined -


in table 1st column has tags href's , 3rd column has text. so, want save href's array respective 3rd column matches string , use later purpose. had tried following code nothing seems wrong me, can 1 assist me this.

function findimagelinks(){      var rows = jquery(".sortable tr.even").length + jquery(".sortable tr.odd").length;      var imglinks = [];            (i=0; i<rows; i++){          var conditionvalue =jquery(".sortable tr:eq(i+1) td:eq(3)").text();          if(conditionvalue == "some string"){              imglinks[i] = jquery(".sortable tr:eq(i+1) td:eq(0) a").attr('href');          }      }      console.log(imglinks);  }    findimagelinks();

your selector wrong. concatenate strings this

var conditionvalue = jquery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();

then code like,

 (i = 0; < rows; i++) {      var conditionvalue = jquery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();      if (conditionvalue == "some string") {          imglinks[i] = jquery(".sortable tr:eq(" + (i + 1) + ") td:eq(0) a").attr('href');      }  }
