以下是经过修改的完整HTML代码,包括您所需的功能:
```html
<!DOCTYPE html>
<html>
<head>
<title>MathJax Example</title>
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"></script>
<style>
.mathjax-formula {
font-size: 2.8em;
background-color: green;
position: absolute;
left: 0;
top: 0;
cursor: move;
padding: 5px;
border-radius: 5px;
color: white;
}
</style>
</head>
<body>
<div id="mathjax-formulas-container"></div>
<script>
var formulas = [];
var selectedDiv = null;
var offsetX = 0;
var offsetY = 0;
document.addEventListener("dblclick", function(event) {
navigator.clipboard.readText().then(function(text) {
if (text) {
var latexCode = text.trim();
if (latexCode) {
var newFormula = document.createElement("div");
newFormula.className = "mathjax-formula";
newFormula.style.left = event.clientX + "px";
newFormula.style.top = event.clientY + "px";
newFormula.innerText = latexCode;
mathjaxFormulasContainer.appendChild(newFormula);
formulas.push({
latexCode: latexCode,
position: {
x: event.clientX,
y: event.clientY
}
});
MathJax.Hub.Queue(["Typeset", MathJax.Hub, newFormula]);
}
}
});
});
document.addEventListener("mousedown", function(event) {
if (event.target.classList.contains("mathjax-formula")) {
selectedDiv = event.target;
offsetX = event.clientX - parseInt(selectedDiv.style.left);
offsetY = event.clientY - parseInt(selectedDiv.style.top);
}
});
document.addEventListener("mousemove", function(event) {
if (selectedDiv) {
selectedDiv.style.left = event.clientX - offsetX + "px";
selectedDiv.style.top = event.clientY - offsetY + "px";
}
});
document.addEventListener("mouseup", function() {
selectedDiv = null;
});
</script>
</body>
</html>
```
请将该代码复制到您的HTML文件中,并根据需要进行任何其他调整和修改。这段代码将实现通过双击释放剪切板上的LaTeX代码,并且可以点击选中<div>并移动,最后鼠标放开停止移动的功能。
