I want to display the content of a label in a text fieldwith onClick event how can I do it,
Is there any specific method to do it or is there any other way.
Please help I am new to ajax.
Thanks
NO need of ajax for this you can do this by using jquery instead simply
In html:
<input type="text" name="txt1" value="" id="txt"/>
<label for="checking" id="label">checking</label>
<input type="submit" name="submit" value="Click" id="butt" />
In Javascript:
$("#butt").click(function(){
var lab_val = $("#label").text();
document.getElementByID("txt").value =lab_val;
// or $("#txt").val(lab_val);
});

I have a form where I would like to hide the submit button unless the input is focussed/selected.
There is only one input apart from the submit.
I need to do this using pure JS (or perhaps CSS/Sass), not jQuery etc.
Basic example:
<form>
<input type="text" placeholder="Example field">
<input type="submit value="Submit">
</form>
First get references to your objects, so change the HTML for example :
<form>
<input id="input_1" type="text" placeholder="Example field">
<input id="submit" type="submit" value="Submit" />
</form>
With some CSS we will hide the submit by default:
#submit{
display:none;
}
We have added Id's, now we add the event listeners for focus on input..
document.getElementById("input_1").addEventListener('focus', function(){
document.getElementById("submit").style.display = 'block';
}
, true);
The second param into the eventListener will execute when the event is fired..
You will need to do more work on this..

Here is the pure CSS solution;
.showonfocus{
display:none;
}
.inputfield:focus + .showonfocus{
display:inline;
}
<form>
<input type="text" placeholder="Example field" class="inputfield">
<input type="submit" value="Submit" class="showonfocus">
</form>
You can use the onblur and onfocus events to manipulate your html elements. You can try something like,
HTML
<form>
<input type="text" placeholder="Example field" onblur="setVisible('hidden');" onfocus="setVisible('visible');">
<input id="submit" type="submit" value="Submit" style="visibility:hidden">
</form>
Javscript
function setVisible(state) {
document.getElementById("submit").style.visibility = state;
}
Here is the working DEMO: https://jsfiddle.net/qbotxpL6/
Hope this helps!
Im trying to call a js function on a HTML element which I have appended to the page using JQUERY.
<body>
<div id='father'>
</div>
<input type="submit" value="choice one" onclick='choice_one()'/>
<input type="submit" value="choice two" onclick='choice_two()'/>
<input type="submit" value="choice three" onclick='choice_three()'/>
</body>
My jQuery is in a js function..
<script>
function choice_one(){
var container = "<div id='field'>
<form>
<input type="text" id='choice_one_answer' value="" />
<input type="submit" value="submit" onclick='answer_one()'/>
</form>
</div>";
$('ul#field').remove();
$("div#father").append(container);
}
function choice_two(){
var container = "<div id='field'>
<form>
<input type="text" id='choice_two_answer1' value="" />
<input type="text" id='choice_two_answer3' value="" />
<input type="submit" value="submit" onclick='answer_two()'/>
</form>
</div>";
$('ul#field').remove();
$("div#father").append(container);
}
</script>
So the third part is using the answers and with js then reloading anther field. Then loading another function --> new answer field.
<script>
function answer_one(){
var answer = document.getElementById('choice_one_answer');
do something with answer...
choice_two();
}
function answer_two(){
var answer_one = document.getElementById('choice_two_answer1');
var answer_two = document.getElementById('choice_two_answer2');
do something with answer...
choice_one();
}
other functions....
</script>
So when I try to call the js functions eg answer_one()/ answer_two() the function cannot grab the variable from the input Id's ---> i presume their is because the element were not loaded when the page loaded!
Is there a jQuery/ js workaround for this... any thoughts??
Is there a work around for something like this??
I think it's a good practice to append html in one line, like this:
var container = "<div id='field'><form><input type="text" id='choice_one_answer' value="" /><input type="submit" value="submit" onclick='answer_one()'/></form></div>";
Don't have the time to test anything, but the jQuery workaround for accessing inserted code is .live()
Why are you using jQuery but not using $()/jQuery() selector for selecting the element?
Try to comment out the //$('ul#id').remove() line and dupm $('ul#id').size() to console in order to know that your element exists.
I have few search forms and each form has an input value with class "search_input".
I want: on button click to add this:
<input type="submit" class="searchbtn" value="Search" />
next to each input
<input type="text" class="search_input" autocomplete="off">.
Currently I am doing so using display none and on click im setting the display to block but the forms are too many so in order to save some kb's instead of typing that on every form, I'm asking if it possible with jQuery to add the input next to each .search_input
Thanks alot
Using jquery it's quiet easy to add control:
$('.search_input').after($('<input type="submit" class="searchbtn" value="Search" />'));
var $input = $('<input type="submit" class="searchbtn" value="Search" />');
$(".search_input").after($input);
//OR
//$input.insertAfter(".search_input");
$("#button_id").click(function(){
$('<input type="submit" class="searchbtn" value="Search" />').insertAfter(".search_input");
});
see docs: http://api.jquery.com/insertAfter/
$('#addSubmitButtons').click(function(e){
$('.search_input').after('<input type="submit" class="searchbtn" value="Search" />');
});
I'm using the jQuery .serialize function and can't get it to serialize the proper form on submit.
my js code:
function getquerystring(form) {
return $("form").serialize();
}
my forms:
<div class="leave_message_box">
<form name="leave_message_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="leave_message" />
<input value="Leave Message" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "leave_message_form")'></p>
</form>
</div>
<div class="outside_job_box">
<form name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
I must be doing something wrong in passing the variable. the full code # pastie. The function I have does work, however, its always the last form that gets submitted.
Using this code:
$("form")
will find all the <form> elements in your document.
Given that form is a string containing the name of the form, what you want instead is this:
$("form[name='" + form + "']")
Looking at your supplied code, I have this suggestion. Instead of passing the form name to your function, why not just pass the form itself?
<button onclick="xmlhttpPost('blah', this.form)">
You also don't need to put javascript: in the onclick, onfocus, onwhatever properties.
I would suggest putting an ID attribute on the form and then using that ID as an explicit selector for jQuery:
<div class="outside_job_box">
<form id="outside_job_form" name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
Then you would select and serialize it like this;
var f = $("#outside_job_form").serialize();
Not only making your code more effecient but more readable, in my opinion.
If the sole purpose is to encode simple text into URL format then use encodeURIComponent().
How can I submit the value of this slider to a CGI application (like you would a check box)?
Not sure if the input tag for the slider is messing something up?
<div class="slider" id="slider-1" tabIndex="1">
<input class="slider-input" id="slider-input-1"
name="slider-input-1"/>
</div>
If I were you, I'd try tweaking the <input> tag's type attribute, setting it to text or hidden.
(I don't know enough about the framework/environment you're using to say for sure.)
OK got it:
<form action="/cgi-bin/Lib.exe" method=POST name="slider" ID="Form2">
<input type="hidden" name="user" value="" ID="Text1">
</form>
<input type="button" value="Delete" class="btn" onclick="setval()" onmouseover="hov(this, 'btn btnhov')" onmouseout="hov(this, 'btn')" ID="Button1" NAME="Button1"/>
function setval()
{
//alert(s.getValue());
document.slider.user.value = s.getValue();//set value of hidden text box to value of slider
document.slider.submit();
}
