所以我試圖制作一個在線計算器并制作了一個js腳本我的問題是如何將此腳本添加到我的html中我嘗試使用腳本但它沒有做任何事情function motion1() {var right=0;var initvel = calc.initvel.value;var finalvel = calc.finalvel.value;var time = calc.time.value;var accl = calc.accl.value;var dist = calc.dist.value;var complete="you have entered more than 3 values. Please leave two text box empty. Other two text box  will be calculated based on that";var incomplete="Sorry! incomplete information";var validinput="You have not entered numeric values!!";if (isNaN(calc.initvel.value)) return alert(validinput);if (isNaN(calc.finalvel.value)) return alert(validinput);if (isNaN(calc.time.value)) return alert(validinput);if (isNaN(calc.accl.value)) return alert(validinput);if (isNaN(calc.dist.value)) return alert(validinput);if(initvel!="" && finalvel!=""  && time!=""  && accl !="" ) return alert(complete);if(initvel!="" && finalvel!=""  && time!=""  && accl !="" && dist !=""   ) return alert(complete);if(initvel!="" && finalvel!=""  && time!=""  ){accl=(finalvel-initvel)/time; calc.dist.value= initvel*time + .5*accl*time*time;calc.accl.value=acclright++;}if(initvel!="" && finalvel!=""  && accl!=""  ){time=(finalvel-initvel)/accl; calc.dist.value= initvel*time + .5*accl*time*time;calc.time.value=timeright++;}if(initvel!="" && time!=""  && accl!=""  ){initvel=parseFloat(initvel);calc.finalvel.value=initvel + (accl*time); calc.dist.value= initvel*time + .5*accl*time*time;right++;}if(finalvel!="" && time!=""  && accl!=""  ){initvel=finalvel - (accl*time); calc.dist.value= initvel*time + .5*accl*time*time;calc.initvel.value=initvelright++;}if(dist!="" && time!=""  && accl!=""  ){initvel=(dist - .5*accl*time*time )/time; calc.finalvel.value= initvel*time + accl*time;calc.initvel.value=initvelright++;}這是牛頓運動學(xué)方程計算器，如果它有任何幫助，它應(yīng)該看起來像這樣， 在此處輸入圖像描述所以它會問我這個值，它應(yīng)該能夠解決其他領(lǐng)域
