我有以下JavaScript变量:
var fontsize = "12px"
var left= "200px"
var top= "100px"
我知道我可以像这样迭代地将它们设置为我的元素:
document.getElementById("myElement").style.top=top
document.getElementById("myElement").style.left=left
有没有可能把它们都放在一起，就像这样?
document.getElementById("myElement").style = allMyStyle
当前回答
var styles = {
"background-color": "lightgray",
"width": "500px",
"height": "300px"
};
/
var obj = document.getElementById("container");
Object.assign(obj.style, styles);
其他回答
var styles = {
"background-color": "lightgray",
"width": "500px",
"height": "300px"
};
/
var obj = document.getElementById("container");
Object.assign(obj.style, styles);
这是一个旧线程，所以我认为对于任何寻找现代答案的人来说，我建议使用Object.keys();
var myDiv = document.getElementById("myDiv");
var css = {
"font-size": "14px",
"color": "#447",
"font-family": "Arial",
"text-decoration": "underline"
};
function applyInlineStyles(obj) {
var result = "";
Object.keys(obj).forEach(function (prop) {
result += prop + ": " + obj[prop] + "; ";
});
return result;
}
myDiv.style = applyInlineStyles(css);
在Javascript中设置多个css样式属性
document.getElementById("yourElement").style.cssText = cssString;
or
document.getElementById("yourElement").setAttribute("style",cssString);
例子:
document
.getElementById("demo")
.style
.cssText = "margin-left:100px;background-color:red";
document
.getElementById("demo")
.setAttribute("style","margin-left:100px; background-color:red");
因为字符串支持添加，你可以很容易地添加你的新样式，而不需要覆盖当前的样式:
document.getElementById("myElement").style.cssText += `
font-size: 12px;
left: 200px;
top: 100px;
`;
<button onclick="hello()">Click!</button>
<p id="demo" style="background: black; color: aliceblue;">
hello!!!
</p>
<script>
function hello()
{
(document.getElementById("demo").style.cssText =
"font-size: 40px; background: #f00; text-align: center;")
}
</script>
