Don't use split不要使用拆分
const arr = [...document.querySelectorAll('tr')].map(tr => tr.outerHTML) console.log(arr) // if the source is a string: const tblString = `<table style="width:100%"><tr><th>Firstname</th></tr><tr><td>Jill</td></tr><tr><td>Eve</td></tr><tr><td>John</td></tr></table>` const domFragment = document.createElement('div') domFragment.innerHTML = tblString; const arr1 = [...domFragment.querySelectorAll('tr')].map(tr => tr.outerHTML) console.log(arr1)
<:DOCTYPE html> <html> <body> <h2>Basic HTML Table</h2> <table style="width:100%"> <tr> <th>Firstname</th> </tr> <tr> <td>Jill</td> </tr> <tr> <td>Eve</td> </tr> <tr> <td>John</td> </tr> </table> </body> </html>
