This is my HTML
<form>
<p>
Enter the total stock value: <input id="total" type="number"onkeyup="calculate()">
</p>
<p>
Enter the agreed commision rate:<input id="commision" type="number">
</p>
<p>
<input id="calculate" type="number" readonly="readonly" placeholder="Result">
</p>
</form>
and this is my Javascript
calculate = function() {
var total = document.getElementById('total').value;
var commision = document.getElementById('commision').value;
document.getElementById('calculate').value = parseFloat(total) / 100 * parseFloat(commision);
}
$(document).keyup(function(e) {
if(e.keyCode== 27) {
$("form")[0].reset();
}
});
Now, if my form is not wrapped in a form tag my Calculate function works perfectly, but when it's in a form tag I'll get an error in the console saying "Uncaught TypeError: calculate is not a function". I tried without the form tag, but then the reset() function is not working..
Does anyone have any idea how to solve this issue?
那是因为你有ID计算元素,元素的IDS被复制的形式,对象的属性(也窗口属性),所以你的情况calculate
已经覆盖了形式的范围内使用时,指的是DOM元素功能
<input id="txtcalculate" type="number" readonly="readonly" placeholder="Result">
