I am working on a simple form demo and i would like the input to display in a below the form. Currently i have it populating in the console. How do i may it display in the div when i click the submit button?
My code:
$(document).ready(function() {
$('.submitForm').on('click',function(event){
event.preventDefault();
$('#firstName').val();
$('#lastName').val();
$('#phoneNumber').val();
$('#address').val();
console.log($('#firstName').val());
console.log($('#lastName').val());
console.log($('#phoneNumber').val());
console.log($('#address').val());
});
});
Well, you're currently not putting the values anywhere but into the console.log.
I would expect to see something like (let's call your div you want the values to go to, "output"):
$(document).ready(function() {
$('.submitForm').on('click',function(event){
event.preventDefault();
// Borrowing from another response, this is better
// Putting these in variables protects you from
// 1) accidentally modifying your form values
// 2) invalid input, if you add some basic checks, like
// testing to see if the length is > 0, doesn't contain
// bad characters, etc.
var firstName = $('#firstName').val(),
lastName = $('#lastName').val(),
phone = $('#phoneNumber').val(),
address = $('#address').val();
// get a reference to the div you want to populate
var $out = $("#output");
// This is a better way of dealing with this
// because every call to .append() forces DOM
// reparsing, and if you do this too often, it can cause
// browser slowness. Better to put together one string
// and add it all at once.
$out.html("<p>" + firstName + "</p>" +
"<p>" + $('#lastName').val() + "</p>" +
"<p>" + $('#phoneNumber').val() + "</p>" +
"<p>" + $('#address').val() + "</p>");
});
});
$(document).ready(function() {
$('.submitForm').on('click',function(event){
event.preventDefault();
$(this).after('<div>First name: '+$('#firstName').val()+'<br>'+
'Last name: '+$('#lastName').val()+
' .... ');
});
});
First of all, the four lines where you read the .val() but don't do anything with it are essentially wasted cycles, you probably meant to store them in variables:
var firstName = $('#firstName').val();
var lastName = $('#lastName').val();
var phoneNumber = $('#phoneNumber').val();
var address = $('#address').val();
To show them in some other element, use the setter version of .val() for input types, or .text() if it's a display type (div, span, etc):
$('#someOtherElement').text(firstName + '\n' +
lastName + '\n'
phoneNumber + '\n'
address);
$(document).ready(function() {
$('.submitForm').on('click',function(event){
event.preventDefault();
//$('#firstName').val();
//$('#lastName').val();
//$('#phoneNumber').val();
//$('#address').val();
var htmlContent = $('#firstName').val() + '<br />' + $('#lastName').val() + '<br />' + $('#phoneNumber').val() + '<br />' + $('#address').val();
$('#ID_OF_YOUR_DIV_HERE').html(htmlContent);
});
});
Maybe this is what you're after??
You can add it to a div you want with .append(), for example
$("#divYouWantToAddTo").append($('#firstName'));
I don't know where to start... What is all that $('#....').val() in the middle there, wasting time only to throw away the result..?
What is wrong with document.getElementById('...').value instead of wasting time creating an entire jQuery object just to access something trivial?
Adding text to a node is as simple as container.appendChild(document.createTextNode(sometext)); - and if you want to have newlines between them you can also do container.appendChild(document.createElement('br'));.
There is no need for jQuery here at all...

I'm using jQuery to get values from ajax rest call, I'm trying to concatenate these values into an 'a' tag in order to create a pagination section for my results (picture attached).
I'm sending the HTML (divHTMLPages) but the result is not well-formed and not working, I've tried with double quotes and single but still not well-formed. So, I wonder if this is a good approach to accomplish what I need to create the pagination. The 'a' tag is going to trigger the onclick event with four parameters (query for rest call, department, row limit and the start row for display)
if (_startRow == 0) {
console.log("First page");
var currentPage = 1;
// Set Next Page
var nextPage = 2;
var startRowNextPage = _startRow + _rowLimit + 1;
var query = $('#queryU').val();
// page Link
divHTMLPages = "<strong>1</strong> ";
divHTMLPages += "<a href='#' onclick='getRESTResults(" + query + "', '" + _reg + "', " + _rowLimit + ", " + _startRow + ")>" + nextPage + "</a> ";
console.log("Next page: " + nextPage);
}
Thanks in advance for any help on this.
Pagination
Rather than trying to type out how the function should be called in an HTML string, it would be much more elegant to attach an event listener to the element in question. For example, assuming the parent element you're inserting elements into is called parent, you could do something like this:
const a = document.createElement('a');
a.href = '#';
a.textContent = nextPage;
a.onclick = () => getRESTResults(query, _reg, _rowLimit, _startRow);
parent.appendChild(a);
Once an event listener is attached, like with the onclick above, make sure not to change the innerHTML of the container (like with innerHTML += <something>), because that will corrupt any existing listeners inside the container - instead, append elements explicitly with methods like createElement and appendChild, as shown above, or use insertAdjacentHTML (which does not re-parse the whole container's contents).
$(function()
{
var query=10;
var _reg="12";
var _rowLimit="test";
var _startRow="aa";
var nextPage="testhref";
//before divHTMLPages+=,must be define divHTMLPages value
var divHTMLPages = "<a href='#' onclick=getRESTResults('"+query + "','" + _reg + "','" + _rowLimit + "','" + _startRow + "')>" + nextPage + "</a>";
///or use es6 `` Template literals
var divHTMLPages1 = `` + nextPage + ``;
$("#test").append("<div>"+divHTMLPages+"</div>");
$("#test").append("<div>"+divHTMLPages1+"</div>");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="test"></div>
I am trying to pass arguments to onclick event of dynamically generated element. I have already seen the existing stackoveflow questions but it didn't answer my specific need.In this existing question , they are trying to access data using $(this).text(); but I can't use this in my example.
Click event doesn't work on dynamically generated elements
In below code snippet, I am trying to pass program and macroVal to onclick event but it doesn't work.
onClickTest = function(text, type) {
if(text != ""){
// The HTML that will be returned
var program = this.buffer.program;
var out = "<span class=\"";
out += type + " consolas-text";
if (type === "macro" && program) {
var macroVal = text.substring(1, text.length-1);
out += " macro1 program='" + program + "' macroVal='" + macroVal + "'";
}
out += "\">";
out += text;
out += "</span>";
console.log("out " + out);
$("p").on("click" , "span.macro1" , function(e)
{
BqlUtil.myFunction(program, macroVal);
});
}else{
var out = text;
}
return out;
};
console.log of out give me this
<span class="macro consolas-text macro1 program='test1' macroVal='test2'">{TEST}</span>
I have tried both this.program and program but it doesn't work.
Obtain values of span element attributes, since you include them in html:
$("p").on("click" , "span.macro" , function(e)
{
BqlUtil.myFunction(this.getAttribute("program"),
this.getAttribute("macroVal"));
});
There are, however, several things wrong in your code.
you specify class attribute twice in html assigned to out,
single quotes you use are not correct (use ', not ’),
quotes of attribute values are messed up: consistently use either single or double quotes for attribute values
var out = "<span class='";
...
out += "' class='macro' program='" + program + "' macroVal='" + macroVal + ;
...
out += "'>";
depending on how many times you plan to call onClickTest, you may end up with multiple click event handlers for p span.macro.
So I have this code that I am trying to alter –
Original:
jQuery(document).ready(function() {
var name = '';
var firstLastName = '[[T6:[[E48:[[S334:fr-id]]-[[S334:px]]:cons.first_name]]]] [[T6:[[E48:[[S334:fr-id]]-[[S334:px]]:cons.last_name]]]]';
var screenname = '[[T6:[[S48:0:screenname]]]]';
if (screenname) {
name = screenname;
} else {
name = firstLastName;
}
var splitName = name.split('');
var nameCheck = splitName[splitName.length-1];
jQuery('#personal_page_header h2').html("Support " + name + "'s Fundraiser" );
});
someone wrote this up and are no longer here, and what I'm trying to do now is figure out how to instead of replace the existing text, add to it.
So right now what this code does is it replaces the h2 content with the constituents registered name, or screenname.
What I'm trying to do now is append to that so that it will say something like
<h2>
Welcome to my fundraiser
<br/>
"Support" + name + "'s Fundraiser"
</h2>
but unfortunately what I tried breaks the code and stops it from working.
what I tried to do is this:
jQuery('#personal_page_header h2').append('<span><br />"Support " + name + "'s Fundraiser"</span>' );
I've tried to do a variety of other things that gave the same unsuccessful result.
Any help would be really appreciated!
Thanks
This should work for you:
jQuery('#personal_page_header h2').append("<span><br/>Support " + name + "'s Fundraiser</span>");
You've just got your quotations a little out of place.
You need to concatenate your code correctly, so if you'd like to keep the " use ' to concatenate. Further you need to escape the ' inside the string with \:
jQuery('#personal_page_header h2')
.append('<span><br />"Support ' + name + '\'s Fundraiser"</span>');
I am new to JQuery.
Trying to create a blog page. When user enters name, country and comment, i want to print it out underneath the HTML form.
The script i'm using is as follows:
<script>
$(document).ready(function() {
$(".addButton").click(function() {
var name = $("input[name=name]").val();
var country = $("select[name=countries]").val();
var comment = $("textarea[name=comment]").val();
$(".comments").append("<div class='new-comment'>" + name + " (" + country + "):</br>" + comment + "</div>");
});
});
This prints out my variables but only for a fracture of a second and they disappear. Any explanation would be highly appreciated.
Thank you.
<button> tags will submit the form, causing the page to reload. Use Event.preventDefault() to stop the form submission.
$(document).ready(function() {
$(".addButton").click(function(e) {
e.preventDefault();
var name = $("input[name=name]").val();
var country = $("select[name=countries]").val();
var comment = $("textarea[name=comment]").val();
$(".comments").append("<div class='new-comment'>" + name + " (" + country + "):</br>" + comment + "</div>");
});
});
I'd like to build a string based on values defined in an html form only if they have been populated. I've successfully parsed the form fields and dropdown with a for loop ($.each()) but my ultimate goal is to dynamically build a string with the results. The string is being used to create a REST query, this is currently the only way to search based on our technologies. Does anyone have a recommended solution?
thx in advance
sample html element:
<input data-param=" prefix like '%" data-name="prefix" class="prefix uno" type="text" placeholder="pre">
working btn click event loop to capture filled in form fields:
var children = $(this).parent().children('.uno');
$.each(children, function(i, val){
if($(val).val() !== ''){
console.log($(val).data('name') + " "+ $(val).data('param') + " " + $(val).val());
}
});
goal:
var newString = field1.param + field1.val + '% ' + field2.param + field2.val + '% ';
translated:
var newString = prefix like '%01%' and name like '%tree%';
Thanks David Fregoli for the jquery serialize reference, that was close, but the solution ended up being to place the strings into a single array, change it toString(), and remove the ',' from the new string.
code:
var samp = [],
thisVal = $(this).parent().children('.uno');
$.each(thisVal, function(i, val){
if($(val).val() !== ''){
samp.push(
$(val).data('param'),
$(val).val(),
$(val).data('close')
);
}
});
itQuery.where = samp.toString().replace( /,/g , '');
result search string:
"number like '%08%' and field = 34"
