我試圖添加一個 if 條件。條件一如果預(yù)付款低于35%價格則"Your downpayment should be above 35% of the price"條件二如果預(yù)付款高于100%價格則"your downpayment should be below 100% of the price"條件三，如果首付款在 35%-100% 之間，則計算一下。答案在我下面的代碼中不起作用，我哪里出錯了？ if(parseInt(downPayment) < 0.35*parseInt(vprice) || parseInt(downPayment) = parseInt(vprice)) {    document.getElementById("month").innerHTML = "Your downpayment should be minimum 35% of the price - "  +" (↑"+ nf.format((Math.round(vprice*0.35))) +")";    }      else if(parseInt(downPayment) > parseInt(vprice)) {    document.getElementById("month").innerHTML = "Your downpayment should be below 100% of the price - "  +" (↑"+ nf.format((Math.round(vprice*0.100))) +")";    }    else {    document.getElementById("month").innerHTML = " 1st Year Monthly Rental: "+ nf.format((Math.round(month))) + "<br>2nd Year Monthly Rental: " +  nf.format((Math.round(month2))) + "<br>3rd Year Monthly Retal:"+  nf.format((Math.round(month3))) ;  google.script.run.userClicked({    vprice,    downPayment,    rate,    period,    month  });  //sending to HTML by ID  document.getElementById("subL").innerHTML = "Sub Loan - "+  nf.format((Math.round(subL)));  document.getElementById("YearBulk1").innerHTML = "1st Year End Bulk Payment - "+ nf.format((Math.round(YearBulk1))); document.getElementById("YearBulk2").innerHTML = "2nd Year End Bulk Payment - "+ nf.format((Math.round(YearBulk2))); document.getElementById("YearBulk3").innerHTML = "3rd Year End Bulk Payment - "+ nf.format((Math.round(YearBulk3)));      }
