javascript - 除了 Window.location.href 之外还有其他方法吗？

Question

我通过使用 Window.location.href 知道。我可以在我的 html 中传递变量，例如:

window.location.href=getone_url+'?proId='+proId

但是现在，我想要类似的东西，但不刷新页面。

谢谢

您可以将值存储在数组中。

然后您可以从同一个数组中检索值。

工作示例:

var listOfNumbers = [];
var button = document.getElementsByTagName('button')[0];
var numberDivs = document.getElementsByTagName('div');

function addNumberToList() {
    listOfNumbers[listOfNumbers.length] = this.textContent;
}

function memoryList() {
var textList = listOfNumbers.join(', ');
window.alert('The numbers you clicked were (in order): ' + textList);
listOfNumbers = [];
}

for (var i = 0; i < numberDivs.length; i++) {
    numberDivs[i].addEventListener('click',addNumberToList,false);
}

button.addEventListener('click',memoryList,false);

div {
float: left;
width: 40px;
height: 40px;
margin: 3px;
line-height: 40px;
text-align: center;
font-weight: bold;
color: rgb(255,255,255);
background-color: rgb(255,0,0);
border-radius: 6px;
}

div:nth-of-type(3n+1) {
clear: left;
}

div:hover {
background-color: rgb(0,127,0);
cursor: pointer;
}

button {
margin-left: 24px;
}

<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
<div>5</div>
<div>6</div>
<div>7</div>
<div>8</div>
<div>9</div>

<button type="button">Tell me what I clicked</button>
