I´m working on a javascript event in dynamics crm 2013.
I have an option set (let´s call it fieldA). When it changes, I want to set the value of a lookup (let´s call it fieldB). This lookup is mandatory (or business required as CRM calls it).
Here is my code:
function fieldAOnChange() {
/* computation of field B value: entityId, name, entityType */
var lookupField = Xrm.Page.getAttribute(fieldBId);
if (!isUndefined(lookupField)) {
if (entityId != null && name != null && entityType != null) {
var lookupValue = new Array();
lookupValue[0] = new Object();
lookupValue[0].id = entityId;
lookupValue[0].name = name;
lookupValue[0].entityType = entityType;
lookupField.setValue(lookupValue);
} else {
lookupField.setValue(null);
}
lookupField.fireOnChange();
}
}
This code works almost fine. The lookup is correctly filled, however the icon "this is a mandatory field and it´s not filled" appears next to the field. This is what I´m trying to fix !
If I click on the field to get the focus and then elsewhere to lose it, the icon disappear. If I change again the value in the option set and the fieldB is updated again, the icon disappear also.
I have tried stupid things like setting the focus on and off or launching the fireOnChange event twice without results.
Am I doing something wrong ?

I have purchased a booking plugin (wordpress) to add to a site.
https://wpamelia.com/
I cannot show the site I am working on, but here a demo from plugin developers
https://sports.wpamelia.com/#book
Once you have chosen your date and time, you end up on a form with input fields.
I was able to pre-fill this form with data that I could pass via the URL.
My URL would look something like this: https://sports.wpamelia.com/?first=Jim&last=Tester&email=something%40something.com&phone=0222222222#book
But here is the problem:
Even though I managed to use jQuery to pre-fill the input fields of the form, as soon as I click confirm the fields' content is erased and the error "Please enter... " appears for each of them.
So again:
STEP 1: I open the booking page with an URL containing data in the query string
STEP 2: Using jQuery, I manage to pre-fill the form that appears after having chosen date and time (first name, last name ...)
STEP 3: I click "Confirm"
RESULT: all the fields are empty and for each one the error message "Please enter first name" (etc..) appears
I've messaged the plugin developers. Only answer was that there is indeed no functionality to take the data from the Query String into the form fields yet.
MY QUESTIONS:
1) How could I find out, with chrome inspector or other tools, why exactly the content I pre-fill into the form is ignored?
---> I've tried things like getEventListeners in the chrome inpector's console, but I don't really see how to get information out of that
2) Would anyone know what the issue is and/or how I could bypass it?
---> there is a lot of javascript from the plugin developers behind that and something is expecting manual entering of the data into the fields...
---> but even when trying to fake manual entering with things like $(this).trigger("change").val(function(i,val){return 'aaaa';}); this didn't solve the problem....
(If anyone is interested, I can post later my javascript/jQuery functionality to get the form fields pre-filled with data from Query String... interesting code as you have to wait until the fields appear for jQuery to recognise them..)
Thanks so much for any help!
cheers

#Admino - this may not be the best solution and I know this is an old question so you may not need it now but after not finding a better one it at least worked for me.
function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}
function valueOutput(element) {
element.dispatchEvent(new Event('input'));
}
jQuery(function() {
jQuery(document).on('change', 'input', function(e) {
valueOutput(e.target);
});
// you may want to perform more validations here if needed
// just checking here if email is present (but not checking for valid email address)
var fname = getUrlVars()["first"];
var lname = getUrlVars()["last"];
var email = getUrlVars()["email"];
var phone = getUrlVars()["phone"];
var custom1 = getUrlVars()["custom1"]; // you know this field label is Order Number
if (email.length > 0) {
// run an interval until the elements are present on the page (form displayed)
var checkInputs = setInterval(function() {
if (jQuery('.amelia-app-booking label[for="customer.email"]').length > 0) {
var em = jQuery('.amelia-app-booking label[for="customer.email"]').closest('.el-form-item').find('.el-input__inner');
// this checks to see if an Amelia customer is already present
if (em.val() == '') {
em.prop('value', email).val(email).trigger('change');
jQuery('.amelia-app-booking label[for="customer.firstName"]').closest('.el-form-item').find('.el-input__inner').prop('value', fname).val(fname).trigger('change');
jQuery('.amelia-app-booking label[for="customer.lastName"]').closest('.el-form-item').find('.el-input__inner').prop('value', lame).val(lame).trigger('change');
jQuery('.amelia-app-booking label[for="customer.phone"]').closest('.el-form-item').find('.el-input-group__prepend').siblings('.el-input__inner').prop('value', phone).val(phone).trigger('change');
}
// for custom fields I check the label text to find the correct input
if (custom1 != '') {
jQuery('.amelia-app-booking label:contains("Order Number")').closest('.el-form-item').find('.el-input__inner').prop('value', custom1).val(custom1).trigger('change');
}
// form info is updated so clear the interval
clearInterval(checkInputs);
}
}, 500);
}
});
You may want to try a different method than url params to sync this info so it's not so public in the url string. This code may not need both the prop and val jquery setters but I just left them for you to try. Hope it helps (and to others I'm open to a better solution)!
I am at the very beginning with my Angular learning and I implemented this form:
http://codepen.io/jgrecule/pen/WxgqqO
What it is supposed to do is very basic: it consumes Flickr public JSONP feed as per Flicker specs https://www.flickr.com/services/feeds/docs/photos_public/ and renders the retrieved pictures thumbnails
The form I implemented has a submit button as well as a reset one. My problems I am trying too find solutions in the order of their importance are:
The very first time when you typing tags everything works but when u try to submit the request again by either adding a new tag or an user Id or anything it no longer works. I can see this warning in the logs but I have no idea what is causing it WARNING: Tried to load angular more than once.
The reset only works for the thumbnails but not for the other controls in my page
I would like to find a way to show an error message when the user pushes on the search flicker button and both tags and user ids input fields are empty. I tried to implement a custom directive but it was no way to get it working.
Thank you in advance for your inputs.
You are loading Angular more than once.
Your resetForm function doesn't reset the form at all. It just calls $setValidity on two of the form elements. It looks like it does try and reset the form in another part of your code with
document.getElementById("searchCriteriaTags").innerHTML = "";
document.getElementById("searchCriteriaIds").innerHTML = "";
document.getElementById("images").innerHTML = "";
which means you are modifying the DOM directly, about which see point 4.
You can add a simple check as to whether $scope.form.tags === '' and so the same for the other fields in your form.
Having addressed your 3 points, I'm afraid to say your code has bigger problems. You are modifying the DOM directly all over the place and you have a lot of duplicate code, plus lots of very complex conditionals.
EDIT 1 in response to OP's comment:
The Angular way of clearing form fields would be to simply clear the scope objects that the form fields are bound to. In other words it is as simple as doing something like:
$scope.tags = [] // for arrays
$scope.name = '' // for strings
Because the form fields are bound to these scope variables through the ng-model directive, changing the variables will also change the form fields.
Setting an error message when two fields are empty you can do like this:
$scope.checkFields = function(field1, field2) {
var oneEmpty = field1 === '';
var twoEmpty = field2 === '';
if (oneEmpty && twoEmpty) {
// call the failure message here
}
}
EDIT 2 in response comments:
Firstly good to see that your code is looking a lot cleaner. Secondly, the reason it fails is because in your search function you set the search fields to null, eg searchCriteria.tags = null;. You should set them to empty strings instead: searchCriteria.tags = '';.
I don't know what the purpose of checkFields is so I don't know where you want to place it. If you want to show an error message if the fields are empty then I'd say have checkFields() return a boolean and use ng-show to display the error div if checkFields() === false.
HTML:
<div ng-show="checkFields() === false">Fields can't be empty</div>
JS:
$scope.checkFields = function(field1, field2) {
var oneEmpty = field1 === '';
var twoEmpty = field2 === '';
return (oneEmpty || twoEmpty);
}
I am trying to build a Client Script in ServiceNow - Geneva (function onChange), that does the following:
-> If the user writes something in an empty field a button should appear after change;
This is my code now, it doesn't work -> gives me an X on the form :):
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
//Define the variable and the name of the button
if (g_form.getValue('work_around') != ''){
var items = $$('BUTTON').each(function(item){
if(item.innerHTML.indexOf('Publish Known Error')=== -1){
item.show();
}
});
}
}
Instead of a Client Script, I would recommend using an onChange(<your field>) UI Policy. This can be accomplished by setting a Condition of your field not being NULL or some other value check.
Your UI Policy can then use the .append function to bind your button to an element of your choice.
I have a problem evaluating a hidden field in JavaScript (ASP MVC4)
I am using a model in my View and have a hidden input for a property in the model
#Html.HiddenFor(mdl => mdl.FilterByUser, new { #id = "filterByUserId" })
I have a Helper with a SearchBox, and on enter key pressed I am making the search.
$("#search-box").keydown(function (event) {
var keypressed = event.keyCode || event.which;
if (keypressed == 13) {
var searchValue = $("#search-box").val();
var filterByUser = $("#filterByUserId").val();
debugger;
window.location = "?searchValue=" + searchValue + "&filterByUser=" + filterByUser;
}
});
The problem is that var filterByUser has a value ONLY if I switch on the DeveloperTools and the browser stops in the "debugger".
If the tools are closed, I get "The parameters dictionary contains a null entry for parameter 'filterByUser' of non-nullable type 'System.Boolean' for method "
The other value, searchValue has no problem in being evaluated.
What can I do to fix this?
Thank you, Daniel
I got it. The problem was that the helper was already in a form. If I put a breakpoint/alert in the js keydown handler, it was executed. If not, the controller action was called using form.submit on textarea enter pressed.
My solve: the js handler was removed, and properties in form were adjusted to match the controller action properties.
I'm using mootools in 1 of my projects. I'm working on easy to be customised menu based on sortables.
So here's the issue - I've got the form which contains menu node informations. Form is updated with JS whenever user chooses different node (form is populated with new data). Problem is that "reset" button obviously "remembers" the initial data, so whenever user clicks it, it loads initial data form.
Is there anyway to update the "default" form status, whenever i load new data? (ofc i could write piece of code which do whatever i need, but if there is some simplier solution which allows default "reset" button to work with new data would be much less work to use it :))
Thanks in advance for help
i cant think of anything else except getting a new source through ajax with data prepopulated and replace the innerhtml hence replacing the form itself.
you can use something like toQueryString to serialize the form and then reverse it based upon the mootools-more's String.parseQueryString():
(function() {
Element.implement({
saveFormState: function() {
if (this.get('tag') !== 'form')
return;
this.store("defaults", this.toQueryString());
},
restoreFormState: function() {
if (this.get('tag') !== 'form')
return;
var vals = this.retrieve("defaults");
if (!vals.length)
return;
var self = this;
Object.each(vals.parseQueryString(vals), function(value, key) {
var el = self.getElement("[name=" + key + "]");
el && el.set('value', value);
});
}
});
})();
var f = document.id('f');
// save default
f.saveFormState();
document.getElement("button").addEvent("click", f.restoreFormState.bind(f));
this ough to cover most cases and you can always save a new defaults state. need to test it somewhat with radios and suchlike, though.
here's a basic fiddle with a save/restore: http://jsfiddle.net/UWTUJ/1/
relevant docs: http://mootools.net/docs/more/Types/String.QueryString (more) and http://mootools.net/docs/core/Element/Element#Element:toQueryString (core)
implied reliance on name attributes on all form elements you want to save/restore.
I have previously created more complex save/restore states that even return field CSS class names, validation messages, etc.
