Ajax call using jquery

function makeAjaxRequest(data1,data2,.....,datax){
    $.ajax({
        'type':'POST',
        async: false,
        url: 'http://www.example.com/some_request_url',
        data:{param1:data1,param2:data2,....,paramx:datax},
        success : function(response) {
            console.log(response); // Using this you can check the posted data in browser console window
            return true;// you can process and return the response as required
            //location.reload(); // or you may reload the current page also
        },
        error: function (jqXHR, exception) {
            // If some error is returned, you can check the details below
            var msg = '';
            if (jqXHR.status === 0) {
                msg = 'Not connect.\n Verify Network.';
            } else if (jqXHR.status == 404) {
                msg = 'Requested page not found. [404]';
            } else if (jqXHR.status == 500) {
                msg = 'Internal Server Error [500].';
            } else if (exception === 'parsererror') {
                msg = 'Requested JSON parse failed.';
            } else if (exception === 'timeout') {
                msg = 'Time out error.';
            } else if (exception === 'abort') {
                msg = 'Ajax request aborted.';
            } else {
                msg = 'Uncaught Error.\n' + jqXHR.responseText;
            }
            $('#post').html(msg); // return the error response in your html page or process it further as required
        }
    });
}

 

issue with submit form in ajax success response

Usually when we try to submit the form after ajax call on success response, the form does not’t get submitted.

Like for example in below code:-

$.ajax({
type : “POST”,
url : “to/some/url”,
data : {
userName:userName,
mobileNumber:mobileNumber,
otp:otp
},
dataType : “json”,
success : function(data)
{
if(data.result == true) {
jQuery(“#form_id”).submit();
}else {
return false;
}
}
});

Now why this occur. Since you are calling the submit function from the ajax response, you need to remove the “submit” handler before submitting the form again. I.E. You need to submit the form without doing the ajax call again. Refer below:-

$.ajax({
type : “POST”,
url : “to/some/url”,
data : {
userName:userName,
mobileNumber:mobileNumber,
otp:otp
},
dataType : “json”,
success : function(data)
{
if(data.result == true) {
// Submit this form without doing the ajax call again
jQuery(“#form_id”).unbind().submit();
}else {
return false;
}
}
});

 

Validate date format mm/dd/yyyy by using jquery validation library

First add the custom method to the validation library as below. Can you put this code in your jquery validation file or in your page where you want to validate the date, just before setting your validation rule for your form.

$.validator.addMethod(“dateFormat”,
 function (value, element) {
 return value.match(/^(?:(0[1-9]|1[012])[\/.](0[1-9]|[12][0-9]|3[01])[\/.](19|20)[0-9]{2})$/);
 },“Please enter a date in the format mm/dd/yyyy.”);

Now suppose you are using a datepicker or input field to accept the date in mm/dd/yyyy format like 02/21/2018 as example. You can validate it as below;

 

<form id="your-form-id">
<input id="submission_date" name="submission_date" type="text" />
<input type="submit" value="submitForm" />
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.js">
 <script type="text/javascript">

$("#your-form-id").validate({
 rules: {
 submission_date: {
 required: true,
 dateFormat: true,
 },
 },
 messages: {
 submission_date: {
 required: "Please select or enter the submission date!!.",
 dateFormat: "Submission date should in the format mm/dd/yyyy.",
 },
 },
 errorPlacement: function(error, element) {
 error.insertAfter(element);
 },
 submitHandler: function (formName) {
 formName.submit();
 }
 });
 </script>

Validate date format mm/dd/yyyy in jquery or javascript

<script type="text/javascript">

function isValideDate(datavalue){
 var regexValidDate = /^(?:(0[1-9]|1[012])[\/.](0[1-9]|[12][0-9]|3[01])[\/.](19|20)[0-9]{2})$/;
 return regexValidDate.test(datavalue);
 }

var dateToCheck = '06/01/2011',

if(isValideDate(dateToCheck)){

alert("Given date is valid as per the format of MM/dd/YYYY");

}else{

alert("Given date is not valid as per the format of MM/dd/YYYY");

}

</script>

 

Redirect to another page after a specific time interval

<html>
<body>
<h1>Welcome to my Website</h1>
<h4 id=”msg”>You will be redirected to another page in 5 seconds!</h4>
<script type=”text/javascript”>
function countDown(i, callback) {
callback = callback || function(){};
var int = setInterval(function() {
//document.getElementById(“displayDiv”).innerHTML = “Number: ” + i;
document.getElementById(“msg”).innerHTML = “You will be redirected to backend page in “+i+” seconds!”;
i– || (clearInterval(int), callback());
}, 1000);
}
setTimeout(function(){
countDown(5, function(){
window.location=”[Give your absolute or relative url to redirect]”;
});
}, 3000);
</script>
</body>
</html>

How to fix flash object z-index

If any of your html element is getting hide behind the flash object such as youtube video player, or any flash player/object

Then you should call this function on body load.

function fix_flash_z_index() {
// loop through every embed tag on the site
var embeds = document.getElementsByTagName(’embed’);
for (i = 0; i < embeds.length; i++) { embed = embeds[i]; var new_embed; // everything but Firefox & Konqueror if (embed.outerHTML) { var html = embed.outerHTML; // replace an existing wmode parameter if (html.match(/wmode\s*=\s*('|")[a-zA-Z]+('|")/i)) new_embed = html.replace(/wmode\s*=\s*('|")window('|")/i, "wmode='transparent'"); // add a new wmode parameter else new_embed = html.replace(//i))
new_object = html.replace(//i, ““);
// add a new wmode parameter
else
new_object = html.replace(/<\/object\>/i, “\n“);
// loop through each of the param tags
var children = object.childNodes;
for (j = 0; j < children.length; j++) { try { if (children[j] != null) { var theName = children[j].getAttribute('name'); if (theName != null && theName.match(/flashvars/i)) { new_object = new_object.replace(//i, ““);
}
}
}
catch (err) {
}
}
// replace the old embed object with the fixed versiony
object.insertAdjacentHTML(‘beforeBegin’, new_object);
object.parentNode.removeChild(object);
}
}
}

Example to call this function
$(document).ready(function () {
fix_flash_z_index();
});
