jquery 自定義alert

前因: 由於在移動裝置彈出alert時,特別是在IOS裝置中會出現彈出域名的問題,所以自定義彈出框是必要的;
但是遇到一個問題: 自定義 confirm 無法在回撥函式中賦值,自義定confirm沒有返回Boolean引數,所以在修改或刪除時,點選“確定”只有在回撥函式中開發

專案開發中是參照如下連結開發:

js程式碼

(function () {
  $.MsgBox = {
    Alert: function (title
, msg)
{ GenerateHtml("alert", title, msg); btnOk(); //alert只是彈出訊息,因此沒必要用到回撥函式callback btnNo(); }, Confirm: function (title, msg, callback) { debugger; GenerateHtml("confirm", title, msg); btnOk(callback); btnNo(); } } //生成Html var GenerateHtml = function (type

專案總使用

<div class="hesvit_form">
<form>
<input name="id" type="hidden" value="${userRel.id}">
<input name="userId" type="hidden" value="${userRel.userId}">
<input id="remarkName" name="remarkName" value="${userRel.remarkName}" type="text" maxlength="5" placeholder="請輸入暱稱" />

</form>
</div>
<div class="hesvit_btn" onclick="update_data()">儲存</div>
<div class="hesvit_btn" onclick="del_data()">刪除</div>

<script type="text/javascript">
// 刪除關聯
function del_data() {

$.MsgBox.Confirm("溫馨提示", "您確認要刪除嗎?", 
function() { 
      var d = {};
      var t = $('form').serializeArray();
      $.each(t, function() {
        d[this.name] = this.value;
      });

      $.ajax({
        type : "POST",
        url :  '${ctx}/wx/userRelation/deleteUserRel',
        data : JSON.stringify(d),
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        success:function(result) {
            if(result && result.code == '0') {
                var rstdata = result.data;
                window.location.href = "${ctx}/wx/userRelation/addButtomUserRelation.wxhtml";
            }else {
                $.MsgBox.Alert("訊息",result.message);
            }
        },
        error : function(XMLHttpRequest, textStatus, errorThrown) {
            $.MsgBox.Alert("錯誤訊息","刪除失敗>:"+textStatus);
        }
    });

});

}
</script>

jquery 預設confirm

 var choice = confirm("您確認要刪除嗎?", function() {
    }, null);
    if(choice){
    }
