javascript - problem in onClick action of textbox that doesnt work in firefox but work on IE

Question

hi my bellow code works on IE but doesnt work on latest version of FireFox. my IE version is :11.483.15063 and my Firefox version is 64 . i think that my problem because using parseInt that was not supported in FireFox

function setTabPage() {
                if (trvpnlState == 2) return;
                if (trvpnlState == 1)
                { HidePnl1(); return }
                var cntElm = document.all['frmContent'];
                var top = document.all['GroupTab1_0'].offsetTop;
                var left = document.all['GroupTab1_0'].offsetLeft;
                var tp1 = document.all['TabPage1'];
                tp1.style.width = 0;
                tp1.style.left = event.clientX - parseInt(tp1.style.width.split('px')) - event.offsetX + 170;

                var prnHlt = parseInt(document.all['GroupTab1_0'].parentElement.parentElement.style.height.split('px')[0]);
                tp1.style.top = 30;
                tp1.style.height = 700;
                tp1.style.display = "";

                if (trvpnlState == 0)
                    ShowPnl1();
            }

 function ShowPnl1() {
            if (oInterval != '') window.clearInterval(oInterval);
            oInterval = window.setInterval("ShowHide(1)", 1);
            document.all['TabPage1'].focus();
            trvpnlState = 2;
        }

        function HidePnl() {
            if ((trvpnlState != 1) && (event.srcElement.id == 'TabPage1')) return

            var divTabPage = document.all['TabPage1'];
            if (event.clientX > parseInt(divTabPage.style.left.split("px")[0]))
                return;

            HidePnl1();
        }
