I am Trying to add an onchange function to three separate elements that will rebuild the calendar if the user changes day, month, or year. The page loads and works fine until I change one of the three values, then it returns only the basic calendar with no css formatting, and all of the other elements from the page are gone. No errors are shown in developer tools.
I have looked at many examples online and I think my syntax is correct. I am calling the function initially on page load, which works fine.
<div id="bottomleft">
<script type="text/javascript" onload="buildCalendar();">
</script>
</div>
I am then calling it on change for each of the three elements as shown below.
<input type="number" min="1" max="31" step="1" id="myday" onchange="buildCalendar();">
<select id="mymonth" onchange="buildCalendar();">
<input type="number" min="100" max="2016" id="myyear" onchange="buildCalendar();">
My full CODEPEN is here: http://codepen.io/anon/pen/qbEXpJ however for some reason the calendar is not displaying here, although it works fine in chrome.
Please let me know if you see any errors.
When you are doing:
document.write("foo")
You are actually overriding the entire page, that's why you are getting everything without css format in the OnChange events. Sounds weird that it actually works with the onload, but you can see in CodePen it won't work there. Try to set up a div and write on it:
$("#myDiv").html("foo")

I've encounter a very strange situation. In my troubleshooting, I have added value="test" in the text field and added console.log($('input[name*="name"]').val()); so the whole code looks like this:
$('body').on('click', 'input[type="button"][name*="review"]', function() {
console.log($('input[name*="name"]').val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="textfield-name" placeholder="Required" value="test" >
<input type="button" name="review" value="Review" />
In the console, it will now say "test" as expected. But if I remove "test" from the text field's value and type in something random like "dsa", it will say... nothing at all! Just a blank row in the console! If I add text after test it will only show "test" and not the text I've typed in.
The code I use, is exactly the same as the code above and it worked perfectly the day before yesterday. I have not edited or added anything else during the time between 2 days ago till now, since I was on a one day long trip yesterday.
If I run the code in jsFiddle, it will execute everything as normal.
I also have tested to remove everything in my JavaScript file and only leaved the code above within $(document).ready(function() { ... }. The result is the same as mentioned. This applies also when I tested to remove everything in the HTML file and only kept the input.
I have also tested to replace .val() with .prop('value') but the result is the same.
In short, all text that I type in to the text field, are completely ignored by the website!
Excuse my language, but what the h*** is going one here?! Is this some sort of bug or what?
The problem is now solved, thanks to Rory McCrossan!
The problem was that multiple text fields with the same name, existed on the same page. I added the post ID into a data properties (data="1") and the problem was after that gone.
Many thanks for opening my eyes, Rory!
I am starting with Bootstrap switch.
I have used the demos from http://www.jque.re/plugins/version3/bootstrap.switch/
The problem is that the switch doesn´t shows. It shows only a standard checkbox.
<div class="make-switch" data-on="primary" data-off="info">
<input type="checkbox" checked>
</div>
I also have included the css and js staff.
JSFiddle:
http://jsfiddle.net/crtLwdg4/
What am I missing here?
I just added this to the fiddle and it seems the appearance has changed.
$(function() {
$('.make-switch').bootstrapSwitch();
});
It seems you need to initialize the switch manually. I have only taken a glance at the docs but this actually changed the appearance of the checkbox.
UPDATE
I was able to get it working by adding a name property to the input and changing the jquery accordingly. see this updated fiddle.
Trying to edit a website with Excel VBA. The edits appear to work, but when I use the save button, nothing is saved. Why isn't updated data, which is visible on the screen, being saved?
This code opens a web page in internet explorer, navigates where I want, fills out data, all which show on the screen, using various methods, such as:
For Each objElement In objElementColl
ExtractedName = objElement.outerHTML
If InStr(ExtractedName, "NewPermit") > 0 Then
objElement.Checked = True
and
Set DropDown = objHTML.getElementById("ProjectFile-AccreditedCertifierId")
DropDown.selectedIndex = 1
or
objHTML.getElementsByName(ElementName)(0).Value = ValueCheck
All work and changes appear on the screen. I click save by using:
Set objElementColl = objHTML.getElementsByClassName("btn")
For Each objElement In objElementColl
ExtractedName = objElement.outerHTML
If InStr(ExtractedName, "click: save, enable:") > 0 Then
objElement.Click
ExtractedName = 1
Exit For
End If
Next
Which runs. The issue is it doesn't save the changes from the three pieces above.
What I have tried
Pause my code and manually click save (same issue)
Pause my code, manually change a checkbox and run the code to save (does save the manual change, but not the coded ones
Pause the code and manually change a box and manually save (only manually changed box is saved)
From above, it appears my save click works, but although the boxes are visibly changed and filled out using the code, there is a gap between the visible and the background.
Some HTML source code. Is what Chrome shows me when Inspecting an element I am changing:
<fieldset>
<legend>Proposal</legend>
<div class="col-xs-12 col-sm-8 col-md-6">
<div class="row">
<div class="col-xs-2 form-group">
<label for="ProjectFile_ProposalLot">Lot</label><input class="form-control" data-bind="textInput: ProjectFile().ProposalLot" maxlength="100" name="ProjectFile-ProposalLot" type="text" />
</div>
<div class="col-xs-2 form-group" data-bind="visible: ProjectFile().StateId() != 7 && ProjectFile().StateId() != 5">
<label data-bind="text: ProjectFile().ProposalDpLabel()"></label>
<input class="form-control" data-bind="textInput: ProjectFile().ProposalDp" maxlength="100" name="ProjectFile-ProposalDp" type="text" />
</div>
I searched the source code for the page. I believe this might be important, but I am not a HTML coder. I have shortened it a bit
var ProjectFileEditViewModel=(function(){__extends(ProjectFileEditViewModel,ViewModel.Model);function ProjectFileEditViewModel(){ProjectFileEditViewModel.__super__.constructor.apply(this,arguments);};ProjectFileEditViewModel.prototype.fields=function(){return {"Id":new ViewModel.NumberField(0),"StateId":new ViewModel.NumberField(0),"DefaultOfficeAddressId":new ViewModel.ObservableField(),"Name":new ViewModel.ObservableField(),"ExistingApprovalDate":new ViewModel.DateField("DD/MM/YYYY"),"ProjectClosed":new ViewModel.ObservableField(),"ProposalAddress":new ViewModel.ObservableChildField(exports.AddressViewModel,this),"Zoning":new ViewModel.ObservableField(),"ProposalLot":new return ProjectFileEditViewModel;})();if(exports.ProjectFileEditViewModel==null)exports.ProjectFileEditViewModel=ProjectFileEditViewModel;
There is also this:
Buildaform.model=new Buildaform.ProjectPageViewModel({ ... ,"ProposalLot":null .... }
I think this last one has something to do with it. I do not know if I can change it.
I cannot release the website address or source code publicly.
As the regarding web site can not be shared, I can come up with a just set of hints to try out:
If the web site would implement a simple (pure) HTML form to send the POST request, your solution would be fine. But looking at the HTML you shared
<label data-bind="text: ProjectFile().ProposalDpLabel()"></label>
the data-bind is already suggesting that the data is getting collected/sent by a library. (E.g. Knockout is using that attribute). This library might now collect the data somewhere, and it might get triggered by a "click" or a "key" event in JavaScript. The collected information can then be stored in a hidden DOM element as suggested by GCSDC or directly in a JavaScript variable.
What I would suggest now is to find out which JavaScript framework is used on this page by inspecting the HTML source. At some point there should be a
<script src="<fancy js framework>.js"></script>
tag in the HTML, which should give you the name of the framework. (There can actually be multiple tags of this kind, including custom JavaScript files. These tags do not have to be at the beginning of the HTML document, and can be scattered all over it, so you might have to search for script in the HTML document. One of them should be the main framework, which is sending the request. If you are not sure which one it would be, you have to google all of them and find out.)
Then, research how the the POST (maybe Ajax) request is sent in the JavaScript code on this page, with help from the documentation of the Framework. And then, send the request by executing custom JavaScript from VBA on this page; how this could be done is shown in this post.
Alternatively, you could try to trigger a click (or key) event on the form inputs to make the framework believe you actually typed it in; how this could be done is shown in this post, but this might not work in all cases.
Per your comment that:
Pause my code, manually change a checkbox and run the code to save
(does save the manual change, but not the coded ones
It seems that the problem is with the code setting form controls and not with the code clicking the save button.
This seems to be a problem not related to VBA but with the behaviour of knockout - see this SO post. The pertinent comment is:
Your problem is that ko subscribes on the click event inside the checked binding:
The questioner in that post is having a similar problem to you - they are trying to check a checkbox (to change the view) but it is not updating either the viewmodel, or the underlying model itself. Knockout is a MVVM framework.
The give-away in your question is that your manual changes commit because you perform a click-and-change when performing the action via point-and-click in the browser, but your programmatic method only does the change to the form control, but not the click first.
So, how to solve this via VBA automation through IE?
Based on the solution in the post I referenced above, plus the method here I will hazard the code below as a possible solution, but please note it is untested ...
Basically you need to 'click' on the form element you want to change - and then update the control value. Hopefully the 'clicking' bit will mean that the knockout viewmodel updates per the 'change', and from there, the model data will be written to the database (or whatever):
Your checkbox example:
If InStr(ExtractedName, "NewPermit") > 0 Then
// hopefully this will get knockout to apply the required binding before your change the value
objElement.Click
objElement.Checked = True
Your dropdown example:
Set DropDown = objHTML.getElementById("ProjectFile-AccreditedCertifierId")
// hopefully this will get knockout to apply the required binding before your change the value
Dropdown.Click
DropDown.selectedIndex = 1
Hope that helps - quite the 3-pipe problem! Good luck.
I have asked this question before and also here. However, none of the proposed answers worked. And days after, the problem is still not resolved. Hence my asking again, with a few more details to see if someone could help me get it resolved.
I have an input field that is generated via Ajax from the server-side, and inserted into the current page. My problem is: the jQuery date picker is not working on the input field when it is generated via Ajax, but it works when the field is directly placed in the page.
Below, I include a scaled-down version of my code.
HTML code:
<form id="user-form"></form>
And here's the jQuery code that's supposed to activate the datepicker on it.
$.ajax({
type: "GET",
url: "/inputfield-loader.php" ,
success: function(data) {
$('#user-form').html(data);
$("#datefield").datepicker();
}
});
And here's inputfield-loader.php
<input type="text" name="firstname" id="firstname"></div>
<div><input type="text" name="email" id="email"></div>
<div><input type="text" name="birthdate" id="datefield"></div>
<div><input type="submit"></div>
Everything works fine if the input field is just hard-coded into the page. But when inserted into the DOM as the return string of an Ajax call, the date picker no longer works. However, when I use Chrome to inspect the datefield field, I see that it has added the jQuery datepicker class hasDatepicker to it, indicating that the call to the jQuery.datepicker() method worked. But on click of the field, I don't see the date picker pop up.
As per #dfsq's suggestion, here is the fiddle. It comes closer to the original code: http://jsfiddle.net/35kgsjxk/
You're missing opening div tag in your inputfield-loader.php file, which can cause issue of hiding some elements.
If you're using correct headers and data type in $.ajax it should work as it's working on: http://jsfiddle.net/96d8k2m3/
I was also facing the same issue. I fixed this as,
$(document).bind('click','#datefield',function(){
$('#datefield').datepicker();
})
I would like to get the updated DOM html string for the form elements (e.g. <input type="text">, <input type="radio">, <input type="radio">, <textarea>).
I found this question and I am trying to use the formhtml plugin written by gnarf:
jQuery html() in Firefox (uses .innerHTML) ignores DOM changes
The problem is that it works in Firefox and Chrome but only works partially in IE8 (I have not tested other versions).
If you open the following page in IE8, you can see there is a text box, some checkboxes and radios. Try entering some text and check the checkboxes and radios.
http://jsfiddle.net/e9j6j/1/
Then click on the 'Click' button.
You can see that no matter I am retrieving the html string through the innerHTML property of a native DOM object or by using the formhtml() function of the plugin. The html returned only reflects the changes in the value attribute of the textbox, you can never see the checked="checked" attributes in <input type="radio"> and <input type="checkbox"> even you have already checked them before clicking the button.
Why is this happening, and how I can make it work in IE?
Thanks in advance.
EDIT:
I am sorry. I made some mistakes in my question, now it has been rewritten.
EDIT:
The sample codes were created to demonstrate my problem but I made some mistakes. Both IE7 and IE8 do give expected results (I also did the tests again).
In my original codes, I do not directly use formhtml() function on the $('#div1') but rather clone it before using formhtml() like this:
alert($('#div1').clone().formhtml());
And on IE8 with jQuery 1.3.2, the returned html does not reflect the checked states of those checkboxes and radios, I never thought it would be the problem of the clone() function that's why when I created the sample codes, I did not clone it and so the actual problem failed to be demonstrated.
The updated sample codes are here (with jQuery version changed to 1.3.2):
http://jsfiddle.net/e9j6j/4/
This may show the problem of the clone() function on IE8 (I don't have IE8 right now, I will test it when I am home, I will report later).
EDIT:
I have just did the test. It's really the problem of clone() function in jQuery 1.3.2 on IE8. It fails to copy the states of checkboxes and radios. After changing it to jQuery 1.5.1. It works perfectly.
I tried the test case at http://jsfiddle.net/e9j6j/1/ on IE8 and IE7 and they worked for me.
Steps to replicate problem:
Load http://jsfiddle.net/e9j6j/1/ in IE browser.
Enter text in the text field, check first radio button, check first checkbox.
Press 'Click' button.
Expected result:
Both alerts show value on text field and 'checked' state on first radio & first checkbox.
Actual result:
As expected. However, bear in mind that IE's representation of the DOM means that checked="checked" is actually reported as CHECKED but it is correct.
UPDATED:
Added a test to ensure that the checked state can be copied to a new dom node:
$('#btn1').click(function() {
alert($('#div1').formhtml());
alert(document.getElementById('div1').innerHTML);
var div1 = $('#div1');
div1.clone().insertAfter(div1);
});
This creates another set of fields which retain the original input state.
