jQuery implementation of rising, falling, deleting, adding a line of code method sharing

This article mainly introduces the jQuery implementation method of rising, falling, deleting, and adding a line of code. It is very good and has reference value. Friends in need can refer to it. I hope it can help everyone use jQuery better.

Application scenarios:

Multi-value sorting, classification sorting and other operations

This code is implemented after practice, and the implementation method is simple and Will not be lost (js adds a line of manually filled Input value) input value

Depends on Jquery, does not rely on other extensions

Javascript code

/*
addTableRow 为添加一行按钮的id值
tableAttr 为table的id值
*/
$(function(){
 //添加一行
 $('#addTableRow').on('click',function(e){
  e.preventDefault();
  var _Html = &#39;<tr><td><input type="text" placeholder="" class="input-text" value=""></td>&#39;
    + &#39;<td><a class="sortUp"><i class="Hui-iconfont"></i>上升</a> <a class="sortDown"><i class="Hui-iconfont"></i>下降</a> <a class="sortDel"><i class="Hui-iconfont"></i>删除</a></td></tr>&#39;;
  $(&#39;tbody&#39;, $(&#39;#tableAttr&#39;)).append(_Html);
  bindEvent();
 });
 bindEvent();
});
function bindEvent(){
 $(&#39;.sortDel,.sortUp,.sortDown&#39;).off();
 $(&#39;.sortDel&#39;).on(&#39;click&#39;, function(e) {
  e.preventDefault();
  if (confirm("确定要删除该属性？")) {
   $(this).parents(&#39;tr&#39;).remove();
  }
 });
 // 初始化上升按钮
 $(&#39;.sortUp&#39;).on(&#39;click&#39;, function(e) {
  e.preventDefault();
  var _current = $(this).parents(&#39;tr&#39;);
  if(($(&#39;tr&#39;).index(_current) - 2) >= 0) {
   _current.insertBefore(_current.prev());
  } else {
   alert("已经到顶了");
  }
 });
 // 初始化下降按钮
 $(&#39;.sortDown&#39;).on(&#39;click&#39;, function(e) {
  e.preventDefault();
  var _current = $(this).parents(&#39;tr&#39;);
  _current.insertAfter(_current.next());
 });
}

Achieve the effect
