how to change the style of alert box

2楼-- · 2018-12-31 06:04

The alert box is a system object, and not subject to CSS. To do this style of thing you would need to create an HTML element and mimic the alert() functionality. The jQuery UI Modal box does a lot of the work for you, working basically as I have described: Link.

I know this is an older post but I was looking for something similar this morning. I feel that my solution was much simpler after looking over some of the other solutions. One thing is that I use font awesome in the anchor tag.

I wanted to display an event on my calendar when the user clicked the event. So I coded a separate <div> tag like so:

<div id="eventContent" class="eventContent" style="display: none; border: 1px solid #005eb8; position: absolute; background: #fcf8e3; width: 30%; opacity: 1.0; padding: 4px; color: #005eb8; z-index: 2000; line-height: 1.1em;">
        <a style="float: right;"><i class="fa fa-times closeEvent" aria-hidden="true"></i></a><br />
        Event: <span id="eventTitle" class="eventTitle"></span><br />
        Start: <span id="startTime" class="startTime"></span><br />
        End: <span id="endTime" class="endTime"></span><br /><br />
</div>

I find it easier to use class names in my jquery since I am using asp.net.

Below is the jquery for my fullcalendar app.

<script>
    $(document).ready(function() {
        $('#calendar').fullCalendar({
            googleCalendarApiKey: 'APIkey',
            header: {
                left: 'prev,next today',
                center: 'title',
                right: 'month,agendaWeek,agendaDay'
            },
            events: {
                googleCalendarId: '@group.calendar.google.com'
            },
            eventClick: function (calEvent, jsEvent, view) {
                var stime = calEvent.start.format('MM/DD/YYYY, h:mm a');
                var etime = calEvent.end.format('MM/DD/YYYY, h:mm a');
                var eTitle = calEvent.title;
                var xpos = jsEvent.pageX;
                var ypos = jsEvent.pageY;
                $(".eventTitle").html(eTitle);
                $(".startTime").html(stime);
                $(".endTime").html(etime);
                $(".eventContent").css('display', 'block');
                $(".eventContent").css('left', '25%');
                $(".eventContent").css('top', '30%');
                return false;
            }
        });
        $(".eventContent").click(function() {
            $(".eventContent").css('display', 'none');
        });
    });
</script>

You must have your own google calendar id and api keys.

I hope this helps when you need a simple popup display.

I tried to use script for alert() boxes styles using java-script.Here i used those JS and CSS.

Refer this coding JS functionality.

var ALERT_TITLE = "Oops!";
var ALERT_BUTTON_TEXT = "Ok";

if(document.getElementById) {
    window.alert = function(txt) {
        createCustomAlert(txt);
    }
}

function createCustomAlert(txt) {
    d = document;

    if(d.getElementById("modalContainer")) return;

    mObj = d.getElementsByTagName("body")[0].appendChild(d.createElement("div"));
    mObj.id = "modalContainer";
    mObj.style.height = d.documentElement.scrollHeight + "px";

    alertObj = mObj.appendChild(d.createElement("div"));
    alertObj.id = "alertBox";
    if(d.all && !window.opera) alertObj.style.top = document.documentElement.scrollTop + "px";
    alertObj.style.left = (d.documentElement.scrollWidth - alertObj.offsetWidth)/2 + "px";
    alertObj.style.visiblity="visible";

    h1 = alertObj.appendChild(d.createElement("h1"));
    h1.appendChild(d.createTextNode(ALERT_TITLE));

    msg = alertObj.appendChild(d.createElement("p"));
    //msg.appendChild(d.createTextNode(txt));
    msg.innerHTML = txt;

    btn = alertObj.appendChild(d.createElement("a"));
    btn.id = "closeBtn";
    btn.appendChild(d.createTextNode(ALERT_BUTTON_TEXT));
    btn.href = "#";
    btn.focus();
    btn.onclick = function() { removeCustomAlert();return false; }

    alertObj.style.display = "block";

}

function removeCustomAlert() {
    document.getElementsByTagName("body")[0].removeChild(document.getElementById("modalContainer"));
}

And CSS for alert() Box

#modalContainer {
    background-color:rgba(0, 0, 0, 0.3);
    position:absolute;
    width:100%;
    height:100%;
    top:0px;
    left:0px;
    z-index:10000;
    background-image:url(tp.png); /* required by MSIE to prevent actions on lower z-index elements */
}

#alertBox {
    position:relative;
    width:300px;
    min-height:100px;
    margin-top:50px;
    border:1px solid #666;
    background-color:#fff;
    background-repeat:no-repeat;
    background-position:20px 30px;
}

#modalContainer > #alertBox {
    position:fixed;
}

#alertBox h1 {
    margin:0;
    font:bold 0.9em verdana,arial;
    background-color:#3073BB;
    color:#FFF;
    border-bottom:1px solid #000;
    padding:2px 0 2px 5px;
}

#alertBox p {
    font:0.7em verdana,arial;
    height:50px;
    padding-left:5px;
    margin-left:55px;
}

#alertBox #closeBtn {
    display:block;
    position:relative;
    margin:5px auto;
    padding:7px;
    border:0 none;
    width:70px;
    font:0.7em verdana,arial;
    text-transform:uppercase;
    text-align:center;
    color:#FFF;
    background-color:#357EBD;
    border-radius: 3px;
    text-decoration:none;
}

/* unrelated styles */

#mContainer {
    position:relative;
    width:600px;
    margin:auto;
    padding:5px;
    border-top:2px solid #000;
    border-bottom:2px solid #000;
    font:0.7em verdana,arial;
}

h1,h2 {
    margin:0;
    padding:4px;
    font:bold 1.5em verdana;
    border-bottom:1px solid #000;
}

code {
    font-size:1.2em;
    color:#069;
}

#credits {
    position:relative;
    margin:25px auto 0px auto;
    width:350px; 
    font:0.7em verdana;
    border-top:1px solid #000;
    border-bottom:1px solid #000;
    height:90px;
    padding-top:4px;
}

#credits img {
    float:left;
    margin:5px 10px 5px 0px;
    border:1px solid #000000;
    width:80px;
    height:79px;
}

.important {
    background-color:#F5FCC8;
    padding:2px;
}

code span {
    color:green;
}

And HTML file:

<input type="button" value = "Test the alert" onclick="alert('Alert this pages');" />

Styling alert()-boxes ist not possible. You could use a javascript modal overlay instead.
