는, 텍스트를 가져옵니다 처음 500 개 문자

편집합니다 : 미안, 코드 샘플 질문을하지 읽어 보시기 바랍니다. 결정된.

var node = $('#elt').parent(); 
var text = node.text(); 

while (text.length < 500) { 
    node = node.nextSibling; 
    if (node.nodeType === 1) { 
     text += node.text(); 
    } else if (node.nodeType === 3) { 
     text += node.nodeValue; 
    } 
} 

text = text.slice(0, 500);
