I have a form with a text area input. I'm using JQuery to submit the form via an AJAX request in order to update a database. My problem is that I'm having difficulty retrieving the data from the text area input. If the input has an id of "txtBody" I have tried:
var body = $("#txtBody").val(); // This adds 'undefined' to the database
var body = $("#txtBody").text(); // This adds nothing to the database
var body = $("#txtBody").html(); // This adds 'NULL' to the database
I can't think of how else to access the data. Any ideas?
You say adds to the database. Have you debugged the actual code to make sure you're not just sending the data with one variable name and trying to add it with another? Because if you have a field like this:
<input type='text' id='txtBody' value='test'>
Or like this:
<textarea id='txtBody'>test</textarea>
Doing $('#txtBody').val(); will return the value "test". There's no ifs or buts about it.
Maybe you should post some more of your code so we can spot what is wrong, as I am guessing that's not the actual problem you are having.
The jQuery documentation suggests that val() was not available is older versions of jQuery. Is your version up to date?

I have created JS script that capture user inputs and publish them in another hidden input document.
I confirmed it works because I made the hidden input visible and publish all the input as delimited string.
So far it works fine
but when I try to use the property document in another textarea, ironpython etc.. within the same DXP it is returning blank, even though I can see the string published in the previous text area.
I used this html tags ...
for input property to display the captured data.
jQuery to capture all the inputs
inval=$.....
......
....
then used this to publish them in the input field $('#dfdklsfksldfkslfs').text(inval).blur()
so far all works fine.
but after this when trying to use the document property in textarea, irontpython, within the same DXP, it is returning (BLANK) even though I can see them published in the textarea.
am I missing any steps? do I need to reassign some features?
also I have tried $('#dfdklsfksldfkslfs').val(inval).blur() this won't even publish the data in the inputfield.
here is the update with code
html
<div id='dispInput'> <spotfirecontrold id='dfdklsfksldfkslfs'></div>
jquery
$('button')click(function(){
inval=$('input').map(function(){
return $(this).val(); }).get().join('-');
$('#dfdklsfksldfkslfs').text(inval).blur() //this publish the result but don't assign the data to the document property
})
I am completely lost.
thanks a lot
Try setting timeout in the function (500ms will do).
$('button')click(function(){
setTimeout(function (){
inval=$('input').map(function(){
return $(this).val(); }).get().join('-');
$('#dfdklsfksldfkslfs').text(inval).blur()
}), 500
});
Hope this helps.
I'm trying to get the hash value of the displayed text of jQuery Real Person plugin with the method $(selector).realperson('getHash'), documented on http://keith-wood.name/realPersonRef.html. However this method gives me a wrong hash value for the displayed text. My code is given below.
HTML
<input type="text" class="form-control" name="captcha" id="captcha">
Javascript
hash_val = jQuery("#captcha").realperson('getHash');
console.log(hash_val);
TEXT DISPLAYED => MEMIDH
CONSOLE OUTPUT => 2759770256 which is incorrect
but when I submit the form, server value is correct.
SERVER HASH VALUE => -1064808263 which is correct
what I'm really trying to do is, to get the hash value and send it via AJAX to server along with user entered text so that I can handle the form without submitting. Please help to solve this problem. Thank you.
I have HTML form and I would like to print the HTML form, with the User Filled Information/Content.
Is there exist any way in jQuery or JavaScript to get a HTML Form with user filled values and print it?
This is what I have tried
$(form).html() but it returns only empty form
$(document).find("form").html() which also returned html with empty form.
NOTE: I am not talking about serialize function here. I don't want to submit a form but want to convert form to a printable version by setting input, select background transparent.
You can use
$('form').find('input').each(function( key, value ) {
console.log(value);
});
And to get the data ready for POST or something like it use this
$('form').serialize();
I think I got your issue. What you are actually want is, to print the HTML form, but it should contain the User Input.
First and foremost, you can use the 'window.print()' method. If you want to print only the Form, then you should use some CSS tricks.
I guess, what you are looking is answered in the following SO Questions. Please check out.

If you are still not able to get your solution done, then let me know. Let me see how I can help you. Good Luck.
I am using Flask as the backend. And I wrote a simple form with WTForm, say,
field = StringField('input:', validators=[Required()])
And I write a JQuery to fill it automatically
$('#theidofthefield').val('fillingin');
And I click the submit button in the form but it shows that the field is empty. And I check the request.form.field.data is also empty.
Hope to get a solution.
I have no idea about WTForm but you can check if your field element has got the name attribute, which is required to send back to the backend code.
Your field has to be something like this:
<input type="text" name="thenameofthefield" id="theidofthefield" />
//-----------------^^^^^^^^^^^^^^^^^^^^^^^---name attribute is required.
Another way to fill value is:
$('#theidofthefield').attr('value','filling');
Lets see if it works..
In case variable field is pointer to the object then..
$(field).val('dfsdf') or $(field).attr('value','filling') may work.
I am trying to disable a textbox in SharePoint WSS3 and force a specific value (given by another JavaScript function) but I can't seem to find the right way of doing it. I have come across different issues. Let's say I have a normal single line text value named prova and another one named Description. Description is required, prova is not.
First Issue: If the field IS required, even if there is something in the textbox, SharePoint says otherwise and does not allow me to insert the entry.
$(document).ready(function(){
//var value = someFunction(...);
var value = "test";
$("input[title='Description']").attr("disabled", "disabled");
$("input[title='Description']").val(value);
});
Second Issue: If the field IS NOT required SharePoint doesn't say anything but it inserts a blank value instead of the one given.
$(document).ready(function(){
//var value = someFunction(...);
var value = "test";
$("input[title='prova']").attr("disabled", "disabled");
$("input[title='prova']").val(value);
});
I have a feeling that tells me that there is some kind of SharePoint JavaScript function somewhere that listens for KeyUp or something. I have really no idea what to do now...
EDIT: It looks like the problem is related to disabling the textbox, if I comment the line where I disable the textbox it works in both scenarios. Maybe if I catch the insert request I can re-enable the textbox before SharePoint do the actual post. No idea how to do it though...
Your problem really is related to disabling the textbox first. By default disabled textboxes are not contained in the POST request in IE.
See this post: Disabled form inputs do not appear in the request or this one: how to save data by disabled text box?
What you actually want to do is set the readonly attribute of the field, not disable it (readonly="readonly"). The problem with that is that the readonly state sometimes looks the same as the default state, so you also have to add some CSS to make it look greyed out.
