Hiding a Section on Dynamics 365 using JS

I'm trying to take a field value (that's a two option check box) and if it is checked then set the visibility on a section to be true, and if it's not checked then to set the visibility to false. I have it set on the field to call the function on an on change event.
When I go into the form and either check the box or uncheck the box it gives me a script error.
This is the function I'm using:
function SetProductVisible(){
if (Xrm.Page.getAttribute("ee_productspecific").getValue()){
Xrm.Page.ui.tabs.get(“SubGrids”).sections.get(“Products”).setVisible(true);
}
else{
Xrm.Page.ui.tabs.get(“SubGrids”).sections.get(“Products”).setVisible(false);
}
};
Thank you for your help.
The fields default value is also set to "No"

Ensure that you are using the right quotation marks by replacing “ and ” with ".
As mentioned in the comments, also ensure that you are using the right name for your tab and section, and check the developer console for more information about the error.

here is your solution...
I created a new field on the CRM form called "log_showhide" which is a two option field. You need to edit the code below to match your Section name and field name with the correct values...
Furthermore, I would set the code to run on load of the form as well as on change of your field.
This method is applicable to Microsoft Dynamics 365 v9.x
function hideOrShow(executionContext){
var a = executionContext.getFormContext().getAttribute("log_showhide").getValue();
if (a == 0) {
Xrm.Page.ui.tabs.get("SUMMARY_TAB").sections.get("sampleSection").setVisible(true);
} else {
Xrm.Page.ui.tabs.get("SUMMARY_TAB").sections.get("sampleSection").setVisible(false);
}
}

Rather than doing a custom web resource to show/hide a field or section, I would recommend you go with a Business Rule. With a Business Rule you can set up a simple check of the value of one field and hide other fields based on that.

Another way to hide a section by field's parent. Just refer a field on that section:
function SetProductVisible()
{
var some_section = Xrm.Page.getControl("new_field_on_that_section_name").getParent();
some_section.setVisible(Xrm.Page.getAttribute("ee_productspecific").getValue());
};

Warn on non-ASCII Characters in Django Form

I'm trying to add some client-side Ajax validation of my Django form. I want to warn users, as they are typing in a field, if any of the characters they just inputted are not ascii.
I originally put the basic python to check for ascii characters in my form's clean method. I don't want to do that, though, as I don't want to produce an error but rather just give a warning message and let the user continue with the rest of the form.
try:
field_value.decode('ascii')
except UnicodeEncodeError:
#raise forms.ValidationError("Non-ASCII characters may cause issues in registering your data. Consider removing these characters. You may still submit at your own risk.")
# Just want to show a warning so the user can still submit the form if they wish
I want to show a small warning under the field as the user is typing. I've tried using django-dajax, but am not sure. How can I do this?
EDIT:
To clarify, I want to show the warning before the user submits the form. So, as they are filling out the form...

Use
> <input type="text" pattern="^[\x20-\x7F]+$" id ....>
in html

Use JavaScript to validate that form field.
Example (using jQuery):
<form>
<input name="whatever" id="fieldId">
...
</form>
<script type="text/javascript">
/* Define a function to check the form field value */
function containsAllAscii(str) {
return /^[\000-\177]*$/.test(str); // returns true if all are ASCII characters. false otherwise.
}
/* Now a little jQuery */
$('#fieldId').on('change', function() {
str = $(this).val();
is_valid = containsAllAscii(str);
if (!is_valid) {
window.alert("There are Non-ASCII characters in the input field");
}
});
</script>
The above code will check the given field's value whenever it changes (i.e. loses focus). You can use .on('keyup', ... instead of .on('change', ... which will check the field's value as the user is typing.
Finally, the error message that is shown is just a browser alert. Which is crappy. You can display a beautiful error message, you just need to learn a little more of jQuery. But I hope I've given you a good starting point.

The code for containsAllAscii function is taken from this answer by Juan Mendes.

In your django form, create a custom field and take advantage of the media class.
from django import forms
class MyWidget(forms.TextInput):
class Media:
css = {
'all': ('pretty.css',)
}
js = ('animations.js', 'actions.js')
and set the js to the javascript file you will use for validation. something along the lines of the the other answer

jQuery Validation for onChange or alternative

I have an interactive/editable table that does a number of things when a cell value is changed using onChange="myfunction". The problem is that I need to have a few validations:
maxlength = 1
only letters ^[a-zA-Z]+$
cannot be blank...require = true
However I fear that due to using onChange I may not be able to achieve this.
Here is a working example of my table: http://jsfiddle.net/JEAkX/32/
Here is the jQuery validator code I am hoping to get to work:
$.validator.addMethod(
"legalValue",
function(value, element) {
return this.optional(element) || /^[a-zA-Z]+$/.test( value );
},
alert("Bad Value!")
);
$(document).ready(function() {
$("#wholeTable").validate({
rules: {
cell: {
legalValue: true,
required: true,
maxlength: 1
}
}
});
});
Is it possible to make this work given my current setup using onChange? If not what direction would you recommend taking to converting to a system that would allow for this validation.
If I stay with onChange do I need to great a global array to house the values of the table in the case that someone enters something incorrect and the value is reverted so the table doesn't change?

just had a look at your sources, I'm not sure I understand what is your problem, but your code has one mistake:
<script type="text/javascript" scr="http://view.jquery.com/trunk/plugins/validate/jquery.validate.js"></script>
should be
<script type="text/javascript" src="http://view.jquery.com/trunk/plugins/validate/jquery.validate.js"></script>
not pushing you to solve the puzzle what's the difference is, I could say that path to script file is specifying using src attribute rather than using scr. After I changed that, when I enter "4" in any field, I get warning message about mistake etc. Also I can't enter few characters... So look like it works.. Was it the problem, or I didn't get your question?

Using depends with the jQuery Validation plugin

I've got a form with a bunch of textboxes that are disabled by default, then enabled by use of a checkbox next to each one.
When enabled, the values in these textboxes are required to be a valid number, but when disabled they don't need a value (obviously). I'm using the jQuery Validation plugin to do this validation, but it doesn't seem to be doing what I expect.
When I click the checkbox and disable the textbox, I still get the invalid field error despite the depends clause I've added to the rules (see code below). Oddly, what actually happens is that the error message shows for a split second then goes away.
Here is a sample of the list of checkboxes & textboxes:
<ul id="ItemList">
<li>
<label for="OneSelected">One</label><input id="OneSelected" name="OneSelected" type="checkbox" value="true" />
<input name="OneSelected" type="hidden" value="false" />
<input disabled="disabled" id="OneValue" name="OneValue" type="text" />
</li>
<li>
<label for="TwoSelected">Two</label><input id="TwoSelected" name="TwoSelected" type="checkbox" value="true" />
<input name="TwoSelected" type="hidden" value="false" />
<input disabled="disabled" id="TwoValue" name="TwoValue" type="text" />
</li>
</ul>
And here is the jQuery code I'm using
//Wire up the click event on the checkbox
jQuery('#ItemList :checkbox').click(function(event) {
var textBox = jQuery(this).siblings(':text');
textBox.valid();
if (!jQuery(this).attr("checked")) {
textBox.attr('disabled', 'disabled');
textBox.val('');
} else {
textBox.removeAttr('disabled');
textBox[0].focus();
}
});
//Add the rules to each textbox
jQuery('#ItemList :text').each(function(e) {
jQuery(this).rules('add', {
required: {
depends: function(element) {
return jQuery(element).siblings(':checkbox').attr('checked');
}
},
number: {
depends: function(element) {
return jQuery(element).siblings(':checkbox').attr('checked');
}
}
});
});
Ignore the hidden field in each li it's there because I'm using asp.net MVC's Html.Checkbox method.

Using the "ignore" option (http://docs.jquery.com/Plugins/Validation/validate#toptions) might be the easiest way for you to deal with this. Depends on what else you have on the form. For i.e. you wouldn't filter on disabled items if you had other controls that were disabled but you still needed to validate for some reason. However, if that route doesn't work, using an additional class to filter on (adding and removing with your checkboxes) should get you to where you want to go, but easier.
I.e.
$('form').validate({
ignore: ":disabled",
...
});

Usually when doing this, I skip 'depends' and just use the required jQuery Validate rule and let it handle the checking based on the given selector, as opposed to splitting the logic between the validate rules and the checkbox click handler. I put together a quick demo of how I accomplish this, using your markup.
Really, it boils down to required:'#OneSelected:checked'. This makes the field in question required only if the expression is true. In the demo, if you submit the page right away, it works, but as you check boxes, the form is unable to submit until the checked fields are filled with some input. You could still put a .valid() call in the checkbox click handler if you want the entire form to validate upon click.
(Also, I shortened up your checkbox toggling a bit, making use of jQuery's wonderful chaining feature, though your "caching" to textBox is just as effective.)

Depends parameter is not working correctly, I suppose documentation is out of date.
I managed to get this working like this:
required : function(){ return $("#register").hasClass("open")}

Following #Collin Allen answer:
The problem is that if you uncheck a checkbox when it's error message is visible, the error message doesn't go away.
I have solved it by removing the error message when disabling the field.
Take Collin's demo and make the following changes to the enable/disable process:
jQuery('#ItemList :checkbox').click(function()
{
var jqTxb = $(this).siblings(':text')
if ($(this).attr('checked'))
{
jqTxb.removeAttr('disabled').focus();
}
else
{
jqTxb.attr('disabled', 'disabled').val('');
var obj = getErrorMsgObj(jqTxb, "");
jqTxb.closest("form").validate().showErrors(obj);
}
});
function getErrorMsgObj(jqField, msg)
{
var obj = {};
var nameOfField = jqField.attr("name");
obj[nameOfField] = msg;
return obj;
}
You can see I guts remove the error message from the field when disabling it
And if you are worrying about $("form").validate(), Don't!
It doesn't revalidate the form it just returns the API object of the jQuery validation.

I don't know if this is what you were going for... but wouldn't changing .required to .wasReq (as a placeholder to differentiate this from one which maybe wouldn't be required) on checking the box do the same thing? If it's not checked, the field isn't required--you could also removeClass(number) to eliminate the error there.
To the best of my knowledge, even if a field is disabled, rules applied to it are still, well, applied. Alternatively, you could always try this...
// Removes all values from disabled fields upon submit
$(form).submit(function() {
$(input[type=text][disabled=disabled]).val();
});

I havent tried the validator plugin, but the fact that the message shows for a splitsecond sounds to me like a double bind, how do you call your binders? If you bind in a function try unbinding just before you start, like so:
$('#ItemList :checkbox').unbind("click");
...Rest of code here...

Shouldn't validate the field after disabling/enabling?
jQuery('#ItemList :checkbox').click(function(event) {
var textBox = jQuery(this).siblings(':text');
if (!jQuery(this).attr("checked")) {
textBox.attr('disabled', 'disabled');
textBox.val('');
} else {
textBox.removeAttr('disabled');
textBox[0].focus();
}
textBox.valid();
});

I had the exact same problem.
I solved this by having the radio-button change event handler call valid() on the entire form.
Worked perfect. The other solutions above didn't work for me.

Is there anyway to disable the client-side validation for dojo date text box?

In my example below I'm using a dijit.form.DateTextBox:
<input type="text" name="startDate" dojoType="dijit.form.DateTextBox" constraints="{datePattern:'MM/dd/yyyy'}" value='<c:out value="${sessionScope.adminMessageForm.startDate}"/>' />
So for example, if the user starts to enter "asdf" into the date the field turns yellow and a popup error message appears saying The value entered is not valid.. Even if I remove the constraints="{datePattern:'MM/dd/yyyy'}" it still validates.
Without going into details as to why, I would like to be able keep the dojoType and still prevent validation in particular circumstances.

Try overriding the validate method in your markup.
This will work (just tested):
<input type="text" name="startDate" dojoType="dijit.form.DateTextBox"
constraints="{datePattern:'MM/dd/yyyy'}"
value='<c:out value="${sessionScope.adminMessageForm.startDate}"/>'
validate='return true;'
/>

My only suggestion is to programmatically remove the dojoType on the server-side or client-side. It is not possible to keep the dojoType and not have it validate. Unless you create your own type that has you logic in it.

I had a similar problem, where the ValidationTextBox met all my needs but it was necessary to disable the validation routines until after the user had first pressed Submit.
My solution was to clone this into a ValidationConditionalTextBox with a couple new methods:
enableValidator:function() {
this.validatorOn = true;
},
disableValidator: function() {
this.validatorOn = false;
},
Then -- in the validator:function() I added a single check:
if (this.validatorOn)
{ ... }
Fairly straightforward, my default value for validatorOn is false (this appears right at the top of the javascript). When my form submits, simply call enableValidator(). You can view the full JavaScript here:
