<p contenteditable='true'></p>

可輸入的p怎么限制輸入的字個(gè)數(shù)

問(wèn)題解答

<p contenteditable='true'>1</p>$ele.onkeyup = function(){ var _html = this.innerHTML; if(_html.length > 10){ this.innerHTML = _html.substr(0,10); this.blur(); }}回答2：

設(shè)置innerHTML.length=“字符個(gè)數(shù)”

通過(guò)js來(lái)限制，參考： http://stackoverflow.com/ques...

<p contenteditable='true'></p> <script type='text/javascript'> document.querySelector(’#test’).addEventListener(’keypress’,function(e) { if(this.innerText.length>=10) {e.preventDefault(); } }); </script>
