How to Programmatically Close a Modal with Materialize.css - html

I am using materialize.css and have been trying to programmatically close a modal and then immediately open another.
This is the code I am currently using to open/close:
$('.modal').modal('close', "#modal1");
$('.modal').modal('open', "#modal2");
What actually happens is that when I call these functions, #modal1 closes successfully, but its backdrop remains there as it is.
At exactly the same time, #modal2 opens up and then immediately (in about 200 ms or so) closes back. Again, the backdrop stays unchanged.
Can I please get help to solve this?
The documentation calls jQuery old. So, am I using some depreacated method, and should I use a vanilla JavaScript equivalent for the same? What, if yes?

For Materialize.js version v0.100 and above.
You can call a onClick function() to close/open multiple modals like below:
Button
In below script when OpenCloseModal() function is executed here, it first closes the Modal (#modal1) and then opens the Modal (#modal2)
<script type="text/javascript">
function closeOpenModal() {
$('#modal1').modal('close');
$('#modal2').modal('open');
}
</script>

You can try:
$('#modal1').modal('close');
$('#modal2').modal('open');

No-JQuery way. First you should get an instance of modal that you intend to close. If e.g. on init you write:
var elems = document.querySelectorAll(".modal");
M.Modal.init(elems);
so in elems we have NodeList of all modals, for example we have three modals, to close second one you can say:
elems[1].M_Modal.close();
to open third:
elems[2].M_Modal.open();

function close_modal() {
var elem = document.getElementById("element-id");
var instance = M.Modal.getInstance(elem);
instance.close();
}

Navigating to a page in a custom event doesn't work properly

When I navigate to a page using this event:
this.events.subscribe('liveTrackingEvent', (time, unit) => {
console.log("event triggered");
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
});
everything gets called, also the function GetLiveData(). (I didn't post this function's code because it's irelevant)
However when I look at the page, not 1 element is updating. So this line:
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
doesn't update the searchform control, however when I call this line of code from the page itself without the event getting triggered on another page, it works smoothly and updates the searchform control.
(It's like I'm on a separate thread for some reason), I'm putting this between brackets because it's just a thought.
So my question is: How do I force this page to update itself also when the event is triggered?
Thanks in advance and if you guys need more code just ask, but this is the most relevant code because everything is working just not when it gets called inside the event.
By using page life cycle events instead of custom events from the ionic framework I managed to make this work and even have a cleaner code.
example:
1st page:
GoToLiveTracking(unitID){
this.navCtrl.push(MapPage, {redirected: true, unitID: unitID});
}
2nd page:
ionViewDidEnter(){
if(this.navParams.get('redirected')){
let unit_id = this.navParams.get('unitID');
this.unitSelected = this.completeService.GetUnitByID(unit_id);
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
}
}
I could think of only 1 reason for this behavior. You are updating your form outside of Angular Zone. That’s why the changes are not getting detected.
To fix the issue, wrapped the call of last 2 lines of event into “this.ngZone.run(() => { ... })”.
e.g
this.events.subscribe('liveTrackingEvent', (time, unit) => {
console.log("event triggered");
this.ngZone.run(()=>{
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
});
});

TabIndex - hitting tab moves me to Address Bar - unable to work around this using Focus or +tab indexes

I read several threads that talk about how the Address Bar in IE is basically the first one to get focus when using TAB (MSDN's own docs talk about this).
Yet, I have seen situations where this doesn't always have to be the case....
I have a master page and inside my content area is a formView.
It defaults to INSERT view and can never leave it (they can only insert not edit and reading is handled elsewhere)
So on my page load for the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If fvwLogEntry.CurrentMode = FormViewMode.Insert = True Then
'Set the default field to position the cursor there...hopefully
Dim FCtxtHrEmployeeId As TextBox
FCtxtHrEmployeeId = CType(fvwLogEntry.FindControl("txtHrEmployeeId"), TextBox)
Page.SetFocus(FCtxtHrEmployeeId.ClientID.ToString)
End If
Now that works, when the page loads it sets the cursor to the employeeID text box inside the formview's INSERT template.
HOWEVER, when I hit TAB it takes me to the address bar and THEN if I hit tab again it takes me through the rest of the items on the page.
I set the tab index of the first item to 11 and then incrimented from there (I had read that IE's toolbars have tab indexes too so I thought perhaps using a higher number would bypass those, but again that doesn't REALLY make sense since it would still start at the lowest number, but I gave it a shot thinking it would move forward from where the focus was set.) If I click on the textbox and then hit TAB it DOES move through the page like I would expect.
It is just when the page loads and gets the focus set to the employeeID textbox that hitting tab moves it to the address bar.
I also tried setting the other controls to -1 (those I didn't want it to tab to), still no luck there.
So... what can I do to get around this?
There MUST be a simple way to set the focus to the employeeID textbox and ensure that pressing TAB after that moves to the next control in the formview's insert template and does NOT jump up to the address bar?
The following jquery code seems to be working fine for me..
$(window).load(function () {
$('.myClass :visible:input:enabled:first').focus();
});
$('body').on('keydown', '.myClass :visible:input:enabled:first', function (e) {
if ((e.which == 9) || (e.keyCode == 9)) {
$('.myClass :visible:input:enabled:first').focus();
}
});
I found another better option which is fastest as of what I tried.
Here's the code for that
function handleTabOrder() {
$('.myClass :visible:input:enabled').each(function (index) {
$(this).attr('tabindex', index + 10);
});
$('.myClass :visible:input:enabled:first').keydown(function (e) {
if (e.keyCode == 9 || e.which == 9) {
$("[tabindex=10]").focus();
}
});
}
What I have done here is to assign Tab order to all the visible controls on the page, then I have handled the key down event of only first control(that shifts the control to address bar) and now it shifts the control to next visible input item on the screen..
Its just a work around but works faster than any of the other things mentioned in the thread.
Just write the above function and all it in on-load event of page.
I was having this issue as well. For me, it was being caused by the use of the .select() method in order to bring focus automatically on a text field as soon as the page loaded. I changed my code to instead use JQuery's .focus() method and that resolved the issue.
I faced similar problem in IE. After some analysis I found that, this problem occurs if there is any HTML content outside form.
for example:
<html>
<div id="1">
</div>
<form>
//other code
</form>
</html>
It worked for me, after I moved all HTML inside form tag.
<html>
<form>
<div id="1">
</div>
//other code
</form>
</html>
Have a look at: http://www.w3schools.com/tags/att_global_tabindex.asp
Your txtHrEmployeeId element should have tabindex 1 and all other elements should have higher values.
-1 is not valid
Also verify that the tabindex are correct in the html that gets rendered (right-click in page and "view source").
I realize this is an old post, but an even simpler method is to add a "tab-stop" attribute to the form element with the last tabindex. Then bind a keydown listener and force focus to the first tabindex when the tab-stop is encountered.
Here's a simple example:
<input type="text" tab-stop />
$document.bind("keydown", function(event) {
var attrs = event.currentTarget.activeElement.attributes;
if (attrs['tab-stop']) {
angular.element.find('select')[0].focus();
event.preventDefault();
}
});
};
The answer mentioned in my other post works fine but it made the page take a huge performance hit because with every key press on the page the whole DOM was being searched for the elements.
So I found a new more optimized solution
var myNameSpace = function(){
this.selector = '.myClass :visible:input:enabled:first';
this.myElement = $(selector);
this._body = $('body');
var _self= this;
this._body.on('keydown',_self.selector,function(e){
if ((e.which == 9) || (e.keyCode == 9)) {
_self.myElement.focus();
}
});
};
The general idea being to 'cache' the node to be accessed. No need to traverse the DOM again and again for just selecting.
I had this same problem. It turns out mine was related to the ajax modal popup extenders. a modal popup was being shown, even though technically i could not see it because it was wrapped inside a parent div that was hidden. if you are using modal popup extenders, this could be causing an issue like this.
If you are using JSF or Primefaces, you can make use of:
<p:focus for"formname"></p:focus>

With one click I want to open link in new window and also 2 new tabs in previous window

I want to open image link in new window and also 2 new tabs in previous window at a time .
Kindly tell me how i can do this with html/java script code or whatever way ?
just simply you should add javascript event on image link and use this code;
<a id="test" href="your address for main window"> <img> </img> </a>
<script type="text/javascript">
document.getElementById("test").onclick = function(){
window.open("url to open in new tab",'_blank');
return true;
}
</script>
important to give a return true (or don't using a return in onclick function).
If you wanna do it in only js you can execute two window functions on onclick:
document.getElementById("test").onclick = function(){
window.open("url to open in new tab",'_blank');
window.open("url to open in main window",'_blank');
}
something like that should work. :)
Technically it depends on the individual settings of the users browser to open URLs in tabs or new windows so whatever you use will be subject to those settings and potentially unreliable.

Overridding <a> tag click event to load data in its own <div>

I have an MVC grid which is rendered in by a json call on page load.
On clicking any tag of Grid I need to refresh this grid.
So I wrote this javascript.
$("#SearchGrid a").live("click", function (event) {
var link = event.currentTarget.attributes[0].childNodes[0].wholeText;
$("#SearchGrid").load(link);
return (false);
});
Its working fine with IE9 and other browsers. But I need to make it workable on IE8.
In IE8 its not loading the grid in same div, instead it redirects it to a new page, containing just the grid which is return from json call.
Try this. It uses the attribute href directly instead of your IE proprietary code
$("#SearchGrid a").live("click", function () {
var link = $(this).attr('href');
$('#SearchGrid').load(link);
return false;
}
not sure what the problem might be, but here are some tips on debugging it:
- var link = 'some-page.html'
try to see if you code actually returns any html data in IE8 - if it does then the problem lies in var link = event.currentTarget.attributes[0].childNodes[0].wholeText;
- instead of load(), try to use an $.ajax call or a json call and see waht happens.
I hope these will prove useful

How to make tabs on the web page?

How to make tabs on the web page so that when click is performed on the tab, the tab gets css changed, but on the click page is also reloaded and the css is back to original.
dont use the jquery :D
all of what you needs a container, a contained data in a varable and the tabs
the container is the victim of the css changes.
the tabs will trigger the changing process.
if you have a static content, you can write this into a string, and simply load it from thiss.
if you have a dinamically generated content, you need to create ajax request to get the fresh content, and then store it in the same string waiting for load.
with the tabs you sould create a general functionusable for content loading.
function load(data) {
document.getElementById("victim").innerHTML = data;
}
function changeCss(element) {
//redoing all changes
document.getElementById("tab1").style.background="#fff";
document.getElementById("tab2").style.background="#fff";
element.style.background = "#f0f";
}
with static content the triggers:
document.getElementById("tab1").onclick = function() {load("static data 1");changeCss(document.getElementById("tab1"))};
document.getElementById("tab2").onclick = function() {load("static data 2");changeCss(document.getElementById("tab2"))};
if you want to change the css, you need another function which do the changes.
i tell you dont use the jquery because you will not know what are you doing.
but thiss whole code can be replaced by jquery like this:
$("tab1").click(function(e) {
$("#tab1 | #tab2").each(function() {
$(this).css("background","#fff"); });
$(this).css("background","#00f");
$("#victim").append("static content 1");
});
$("tab12click(function(e) {
$("#tab1 | #tab2").each(function() {
$(this).css("background","#fff"); });
$(this).css("background","#00f");
$("#victim").append("static content 2");
});
if you know how javascript works then there is noting wrong with the jquery, but i see there is more and more people who just want to do their website very fast and simple, but not knowing what are they doing and running into the same problem again and again.
Jquery UI Tabs:
http://jqueryui.com/demos/tabs/
Have a <A href tag around the "tab" and use onClick to fire some Javascript that changes the CSS.
If you do not want use Jquery for creating of UI tabs, please see my cross-browser JavaScript code: GitHub.
You can use different ways to create tabs and tab content.
Tab content can added only when tab gets focus.
You can remember selected tab. Selected tab opens immediatelly after opening of the page.
You can create tabs inside tab.
Custom background of the tab is available.
