javascript - java script checks two input values only by digit -

var tbv = document.getelementbyid("inputfrom");  var tbb = document.getelementbyid("inputto");  var submit_check = document.getelementbyid("checkvalues");      function blr() {    var von = tbv.value;    var bis = tbb.value;      console.log(von);    console.log(bis);      if (von >= bis || bis <= von) {      checkvalues.disabled = true;    } else {      checkvalues.disabled = false;    }    }  tbv.addeventlistener("blur", blr);  tbb.addeventlistener("blur", blr);

from: <br>  <input type="text" class="form-control" pattern="(|-)?[0-9]{0,3}?" title="min: -100" id="inputfrom" />  <br> to: <br>  <input type="number" class="form-control" pattern="(|-)?[0-9]{0,3}?" title="max: 300" id="inputto" />  <br>  <button type="submit" class="btn btn-primary" id="checkvalues"> check </button>

as explained above, want check if value of input "from" greater or equal input "to".

the thing is, works checking digit digit, if input "from" has value 12 , input "to" has value 1, correct.

anyone idea i´m doing wrong?

by default .value returns string, use parseint() parse value number.

note: von >= bis , bis <= von means same. use of 1 enough.

var tbv = document.getelementbyid("inputfrom");  var tbb = document.getelementbyid("inputto");  var submit_check = document.getelementbyid("checkvalues");      function blr() {    var von = parseint(tbv.value);    var bis = parseint(tbb.value);      console.log(von);    console.log(bis);      if (von >= bis) {      checkvalues.disabled = true;    } else {      checkvalues.disabled = false;    }    }  tbv.addeventlistener("blur", blr);  tbb.addeventlistener("blur", blr);

from: <br>  <input type="text" class="form-control" pattern="(|-)?[0-9]{0,3}?" title="min: -100" id="inputfrom" />  <br> to: <br>  <input type="number" class="form-control" pattern="(|-)?[0-9]{0,3}?" title="max: 300" id="inputto" />  <br>  <button type="submit" class="btn btn-primary" id="checkvalues"> check </button>
