根据您给的文本，

文本粘贴操作

javascript document.getElementById.addEventListener { event.preventDefault; const clipboardData = event.clipboardData; const text = clipboardData.getData; const htmlData = clipboardData.getData; const tempDiv = document.createElement; tempDiv.innerHTML = htmlData; const pastedText = tempDiv.textContent || tempDiv.innerText || ''; const pastedHtml = htmlData.replace; this.focus; document.execCommand; });

HTML粘贴操作

javascript document.getElementById.addEventListener { event.preventDefault; const pasteText = event.clipboardData.getData; document.getElementById.innerHTML = pasteText; });

图片粘贴操作

javascript document.addEventListener { const items = e.clipboardData.items; for { if !== -1) { e.preventDefault; const blob = items.getAsFile; const reader = new FileReader; reader.onload = function { const img = new Image; img.src = event.target.result; document.body.appendChild; const canvas = document.createElement; const ctx = canvas.getContext; canvas.width = img.width; canvas.height = img.height; ctx.drawImage; const url = canvas.toDataURL; const a = document.createElement; a.href = url; a.download = 'image.png'; a.click; }; reader.readAsDataURL; } else { e.preventDefault; } } });

JSON粘贴操作

javascript document.addEventListener { const clipboardData = event.clipboardData; const json = clipboardData.getData; console.log; });

XML粘贴操作

javascript document.addEventListener { const items = e.clipboardData.items; for { if !== -1) { e.preventDefault; const blob = items.getAsFile; const reader = new FileReader; reader.onload = function { const xml = event.target.result; console.log; }; reader.readAsText; } else { e.preventDefault; } } });

管束粘贴内容

javascript document.getElementById.addEventListener { event.preventDefault; const clipboardData = event.clipboardData; const pastedData = clipboardData.getData; if ) { return; } this.value = pastedData; });

这些个代码示例展示了怎么处理不同类型的粘贴内容，包括文本、HTML、图片、JSON、XML等，以及怎么管束粘贴内容。在实际应用中，您兴许需要根据具体需求调整这些个代码。
