我正在為分配計(jì)算器編程，并且正在努力將每個按鈕單擊的值附加到我的顯示框。例如，如果我單擊按鈕“ 4”，然后單擊“ 5”，則我希望顯示器輸出“ 45”，依此類推，以便評估顯示框中的內(nèi)容。當(dāng)我單擊計(jì)算器上的一個按鈕時，該數(shù)字將正確顯示，但是此后不會再添加任何并發(fā)值。如果在鍵盤上鍵入顯示，我還創(chuàng)建了equal函數(shù)以正確運(yùn)行。<!DOCTYPE html><head> <link href="project4.css" rel="stylesheet"> <title>Calculator</title> </head> <body> <div id="calculator"> <h3>Calculator</h3> <input type="text" id="display" onClick= "append()"><br /> <input type="button" value="mrc" class="memory"> <input type="button" value="m+" class="memory"> <input type="button" value="m-" class="memory"> <input type="button" value="/" class="operator" onClick= "setDivide()"><br /> <input type="button" value="7" class="number" onClick= "setSeven()"> <input type="button" value="8" class="number" onClick= "setEight()"> <input type="button" value="9" class="number" onClick= "setNine()"> <input type="button" value="*" class="operator" onClick= "setMultiply()"><br /> <input type="button" value="4" class="number" onClick= "setFour()"> <input type="button" value="5" class="number" onClick= "setFive()"> <input type="button" value="6" class="number" onClick= "setSix()"> <input type="button" value="+" class="operator" onClick="setAdd()"><br /> <input type="button" value="1" class="number" onClick= "setOne()"> <input type="button" value="2" class="number" onClick= "setTwo()"> <input type="button" value="3" class="number" onClick= "setThree()"> <input type="button" value="-" class="operator" onClick= "setSubtract()"><br /> <input type="button" value="0" class="number" onClick= "setZero()"> <input type="button" value="." value="." class="number" onClick= "setDecimal()"> <input type="button" value="C" class="clear" onClick= "setClear()"> <input type="button" value="=" class="equal" onClick= "setEquals()"> </div>
