adi*_*din 3 html javascript arrays jquery for-loop
我使用a for-loop
来获取排序列表的值,.html()
但它只打印数组中的最后一个值.我想通过使用myArray.length
并myArray[i]
在循环中它将按预期循环.
理想情况下,我希望这样:
排序值为:1,2,3,4,5等..
我究竟做错了什么?
HTML:
<div id="wrapper">
<div id="content">
<h1>Let's Do Some Math</h1>
<div id="intake">
<input type="text" id="input"> <button id="inTakeButton">Push to Array</button> <button id="showArray">Show Array</button> <button id="doMath">Do Math</button>
</div>
<div id="middle">
<ul id="list">
</ul>
</div>
<div id="output">
<p id="sorted"></p>
<p id="sum"></p>
<p id="average"></p>
</div>
</div>
</div>

JavaScript的:
myArray = [];
var theTotal;
$(document).ready(function() {
$('#inTakeButton').on('click', function() {
var inputValue = parseFloat($('#input').val());
if (inputValue === "") {
return;
}
if (isNaN(inputValue)) {
$('#input').val("");
return;
}
myArray.push(inputValue);
$('#input').val("");
});
$('#showArray').on('click', function() {
console.log(myArray);
$('#list').html("");
for (var i = 0; i < myArray.length; i++) {
$('#list').append("<li>" + myArray[i] + "</ul>");
};
$('#doMath').on('click', function() {
theTotal = 0;
for (var i = 0; i < myArray.length; i++) {
theTotal = theTotal + myArray[i];
};
$('#sum').html("");
$('#sum').html("The sum is: " + theTotal);
var average = (theTotal/myArray.length);
$('#average').html("");
$('#average').html("The mean value is: " + average);
var sorted = myArray.sort();
$('#sorted').html("");
for (var i = 0; i < myArray.length; i++) {
$('#sorted').html("The sorted values are: <br>" + myArray[i] + ", ");
};
});
});
});

你甚至不需要使用数组循环来做到这一点,只需:
$('#sorted').html("The sorted values are: <br>" + myArray.join(", "));
