模態框：
不同的按鈕打開同一個id=myModal的模態框，有時候需要傳入一個參數（flag）來進行區分是哪一個按鈕打開的
那么直接上代碼了
第一個按鈕button屬性里面加入data-whatever="add"
1 <button id="sure_pre_release_draft" type="button" data-toggle="modal" data-target="#myModal" data-whatever="add" class="btn btn-primary btn-sm"> 2 <span class="glyphicon glyphicon-plus"></span> 3 </button>
第二個按鈕button屬性里面加入data-whatever="edit"
1 <button id="sure_pre_release_draft" type="button" data-toggle="modal" data-target="#myModal" data-whatever="edit" class="btn btn-primary btn-sm"> 2 <span class="glyphicon glyphicon-plus"></span> 3 </button>
然后通過模態框觸發事件來獲取
1 $("#myModal").on("show.bs.modal",function(e){ 2 //獲得點擊打開的按鈕 3 var button=$(e.relatedTarget); 4 //根據標簽獲得按鈕傳入的參數 5 var recipient=button.data("whatever"); 6 //console.log(recipient); 7 if(recipient == "edit"){ 8 do something............. 9 } 10 if(recipient == "add"){ 11 do something............. 12 } 13 });
