jQuery删除当前节点元素

//state用来判断获取内容的状态,单击一次获取文本内容,第二次单击删除内容var state = 0;function getfilecontent(btn){//这边用来判断是否已经获取到文本内容,获取到则删除if(state == 1){var td = $(btn).parent().parent().next().children();td.remove();state = 0;return;}var filePath = document.getElementById("filepath").innerHTML.trim();var tr = btn.parentNode.parentNode;var tds = tr.getElementsByTagName("td");var fileName = tds[0].innerHTML.trim();$.post("<%=basePath%>intelligentjournal/getfilecontent.do", {"filePath":filePath,"fileName":fileName},function(fileContent){var file = fileContent;var ntr = document.createElement("tr");ntr.innerHTML = '<td style="border:1px solid black" id = "td">' + file + '</td>';var tr1 = document.getElementById(fileName);tr1.appendChild(ntr);},"JSON");state = 1;}
