jquery 自定義alert
阿新 • • 發佈:2018-11-30
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 , title, msg) {
var _html = "";
_html += '<div id="mb_box"></div><div id="mb_con"><span id="mb_tit">' + title + '</span>';
_html += '<a id="mb_ico">x</a><div id="mb_msg">' + msg + '</div><div id="mb_btnbox">';
if (type == "alert" ) {
_html += '<input id="mb_btn_ok" type="button" value="確定" />';
}
if (type == "confirm") {
_html += '<input id="mb_btn_ok" type="button" value="確定" />';
_html += '<input id="mb_btn_no" type="button" value="取消" />';
}
_html += '</div></div>';
//必須先將_html新增到body,再設定Css樣式
$("body").append(_html); GenerateCss();
}
//生成Css
var GenerateCss = function () {
//獲取當前螢幕的寬度 和高度
var wondWidth = $(window).width();
var wondHeight = $(window).height();
var setWidth = wondWidth * 0.7;
setWidth = setWidth+"px"
var setHeight = wondHeight * 0.2;
setHeight = setHeight+"px"
$("#mb_box").css({ width: '100%', height: '100%', zIndex: '99999', position: 'fixed',

$("#mb_btn_ok").css({ backgroundColor: '#168bbb' });
$("#mb_btn_no").css({ backgroundColor: 'gray', marginLeft: '20px' });
//右上角關閉按鈕hover樣式
$("#mb_ico").hover(function () {
$(this).css({ backgroundColor: 'Red', color: 'White' });
}, function () {
$(this).css({ backgroundColor: '#DDD', color: 'black' });
});
var _widht = document.documentElement.clientWidth; //螢幕寬
var _height = document.documentElement.clientHeight; //螢幕高
var boxWidth = $("#mb_con").width();
var boxHeight = $("#mb_con").height();
//讓提示框居中
$("#mb_con").css({ top: (_height - boxHeight) / 2 + "px", left: (_widht - boxWidth) / 2 + "px" });
}
//確定按鈕事件
var btnOk = function (callback) {
$("#mb_btn_ok").click(function () {
$("#mb_box,#mb_con").remove();
if (typeof (callback) == 'function') {
callback();
}
});
}
//取消按鈕事件
var btnNo = function () {
$("#mb_btn_no,#mb_ico").click(function () {

}
})();
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="${userRel.remarkName}" type="text" maxlength="5" placeholder="請輸入暱稱" />
<input id="accountName" name="accountName" value="${user.userName}" readonly="readonly" type="text" />
</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){
}
