html input element hide and show using link tag.
example:yahoo mail Bcc hide and show
This is done in Javascript.
For simple Javascript, i.e. without using jQuery you can do that:
document.getElementById("idOfElement").style.display = "none"; // to hide
document.getElementById("idOfElement").style.display = "block"; // to show
Here is a link with the possible values for this display CSS element.
yahoo does this with javascript.
using plaing JS on the onlick of a link:
document.getElementById('someDiv').style.display = 'block'; //or 'none' to hide
using a JS library like jQuery:
$('#someDiv').show(); //or .hide();

I am using primefaces documentViewer which is based on mozilla PDF.js: 2.11.338
https://www.primefaces.org/showcase-ext/views/documentViewer.jsf
and I want to customize the viewer to control which buttons to appear in the toolbar like rotate & print & download only.
I couldn't find any guides about that in primefaces website.
There is no JS Widget for Document Viewer however this can be accomplished easily with a JS function like this.
Note: Some buttons like presentationMode are special and need to be hidden a little differently.
pdfHideButtons : function() {
var pdfViewer = $("#YourDivId");
if (pdfViewer) {
$(pdfViewer.contents().find("#openFile")).hide();
$(pdfViewer.contents().find("#viewBookmark")).hide();
}
}
Then on your page add this code to basically hide the buttons after the page loads.
<script>
$(document).ready(function() {
setTimeout(function(){ pdfHideButtons(); }, 1000);
});
</script>
I want to take a tag and replace with a #Html.textarea() razor html helper but it doesn't look as if JQuery can replace DOM elements with html helpers. How do I go about this?
using(#Html.BeginForm())
{
<a id="clickme">Edit</a>
<div>#Model.username</div>
}
How can I replace this div with #Html.Textarea ? JQuery could do it with div and input tags.
jQuery cannot replace a tag with #Html.TextArea() !
The TextArea helper method is a C# method, which gets executed when razor tries to render the view. This happens in your web server. jQuery is a client side library and anything you do with jQuery happens at client side, in your browser.
But all these helper methods ultimately generate some HTML for DOM elements. That means, you can use jQuery to manipulate visibility of that.
If you are trying to do something like an inline edit, you can use a script like this , to start with
First, render the text area along with your label div, but have it hidden initially. Also wrap the label,edit link and the hidden input inside a container div which we can use later to help with our jQuery selectors.
#using (#Html.BeginForm())
{
<div class="edit-item">
Edit
<div class="edit-label">#Model.FirstName</div>
#Html.TextAreaFor(a => a.FirstName,
new { style = "display:none;", #class = "edit-text" })
</div>
<div class="edit-item">
Edit
<div class="edit-label">#Model.UserName</div>
#Html.TextAreaFor(a => a.UserName,
new { style = "display:none;", #class = "edit-text" })
</div>
}
Now when the user clicks edit, you have to toggle the visibility of the label and hidden input and update the value of label after user done editing the value in the input element.
$(function () {
$("a[data-mode]").click(function (e) {
e.preventDefault();
var _this = $(this);
var c = _this.closest(".edit-item");
c.find(".edit-text").toggle();
c.find(".edit-label").toggle();
if (_this.attr("data-mode") === 'label') {
_this.attr("data-mode", 'edit');
_this.text("done");
} else if (_this.data("mode") === 'edit') {
c.find(".edit-label").text(c.find(".edit-text").val());
_this.text("edit");
_this.attr("data-mode", 'label');
}
});
});
This is a head start. You can optimize this code as needed.
Here is a working jsfiddle for your reference
I've created a html page and in that page I have forms, drop down lists and radio tags and tables. from one button I wanted to reset everything on the page when its clicked upon.
you can use the following JavaScript method to clear the HTML input file control's value:
function clearFileInputField(tagId) {
document.getElementById(tagId).innerHTML =
document.getElementById(tagId).innerHTML;
}
Or, if refactored in jQuery, this should work as well:
$("#control").html($("#control").html())
Or, for textbox type
var elements = document.getElementsByTagName("input");
for (var ii=0; ii < elements.length; ii++) {
if (elements[ii].type == "text") {
elements[ii].value = "";
}
}
You could use a reset button, please refer to this page for more information -> LINK
But if you have multiple form on the page you can write a javascript function to reset all of them like this:
$('#yourResetButton').click(function(){
$('form').each(function(idx, obj){
obj.reset();
});
});
You could also refresh your page as stated in other answers but in my opinion that could be very disappointing for your users to see that the page is refreshing
A little working fiddle as example
You can reset with reset however you won't be able to reset your inputs that doesn't included into forms, otherwise you can clear inputs within your forms like:
$('form').each(function (index, obj) { obj.reset(); });
Example
<input type="button" onclick="function() {window.location.href = window.location.href;}" name="Reset" value="Reset">
Is there a way I can use a button(input type="button") to show the Bootstrap modal. Basically the default is using anchor based on the documentation. I have tried experimenting but no luck.
I'm not sure if my coding is wrong or the Bootstrap modal can only be activated if it is an anchor tag. I have also tried googling or researching if anyone has created this kind of result.
This should work the same way as with an anchor tag.
The problem is, it's based on the href attribute, referring to the id of the modal window, and placing this attribute on a button might cause some html validation to go wonky.
If you don't care about that kind of stuff you can just replace your a tag with a button tag.
Edit: just noticed you were using an input element rather than a button. Either way, it should still work.
Edit2: Just verified if what I was saying wasn't total BS by looking at the bootstrap code (2.3.2), and found this snippet:
$(document).on('click.modal.data-api', '[data-toggle="modal"]', function (e) {
var $this = $(this)
, href = $this.attr('href')
, $target = $($this.attr('data-target') || (href && href.replace(/.*(?=#[^\s]+$)/, ''))) //strip for ie7
, option = $target.data('modal') ? 'toggle' : $.extend({ remote:!/#/.test(href) && href }, $target.data(), $this.data())
e.preventDefault()
$target
.modal(option)
.one('hide', function () {
$this.focus()
})
})
Looking at this, the href attribute isn't required, and you can use data-target instead when working with inputs and buttons.
simply u can fire event on Button Click and call function "onclick=showModal()"
JS CODE
function showModal()
{
$("#modal-window-id").modal("show");
}
I would like to add a section to an existing webpage, but only make it visible if the user types the URL with a particular anchor link. Is this possible? Or is it possible to redirect to a new page if the URL has a certain anchor link?
Since you don't mind using JS, you can listen to the onhashchange event to decide whether the specific section should show.
http://jsfiddle.net/C3kHT/
window.addEventListener("hashchange",function(){
if(location.hash=="#trap") /*show section*/
},false);
Sorry that I don't have an IE 8 at hand, so I'm not sure if the fiddle code actually work in IE 8.
To redirect if a url has a certain anchor:
var anchor = "#tag";
var url = "http://www.google.com";
if(window.location.indexOf(anchor) !== -1){
window.location = url;
}
Maybe try this. Start out with your hidden section set to display: none;, then use jQuery to unhide it based on the hash in the url.
CSS:
.hiddenDiv {
display: none;
}
jQuery:
function showDiv() {
if (window.location.hash === '#hashNecessaryToShowDiv') {
$('.hiddenDiv').css('display', 'block');
}
}
showDiv();
