I have a a web page where various fields are shown or hidden by toggling between "display:block" and "display:none". However, I added some extra stuff to the page and discovered that I needed to special-case several tags: TD needs to use "display:table-cell:, TR needs to use "display:table-row", and so on...
Is there any general off-the-shelf solution to this (i.e. look up the "natural" display type based on the tag name) or am I stuck with creating a JS object by hand which lists tag names and the corresponding display types?
You can apply revert to display property to set the element to it's original value and get the original value by Javascript.
const getOriginalDisplayProperty = (elem) => {
const modifiedDisplayProperty = getDisplayProperty(elem); //store modified display property
elem.style.display = "revert"; //revert to original display property
setTimeout(() => {
elem.style.display = modifiedDisplayProperty; // Again set original display property
}, 0);
return getDisplayProperty(elem);
};
const getDisplayProperty = (elem) =>
window.getComputedStyle(elem, null).display;
getOriginalDisplayProperty(document.querySelector(".test"));
getOriginalDisplayProperty(document.querySelector(".test-span"));
div {
display: inline;
}
span {
display: flex;
}
<div class="test"></div>
<span class="test-span"></span>

By default Ag-grid sets a fixed column menu width. Their documentation has an example of setting the column menu width to a different fixed value. The issue with this approach is that every column will have the same menu width.
Is there a way to dynamically set the column menu width based upon the column's filter list values? The following has no effect:
.ag-set-filter-list {
width: auto;
}
Similarly word wrapping could also solve this issue, but is also not working:
.ag-set-filter-list {
overflow-wrap: break-word;
}
I also tried using the postPopup callback to adjust styling after rendering, with no luck:
created() {
this.postProcessPopup = (params) => {
if (params.type !== 'columnMenu') {
return;
}
params.ePopup.style.overflowWrap = "break-word";
params.ePopup.style.width = "auto";
}
}
Digging into Ag-grid's filter list styling more, I realized that the filter items are absolutely positioned and use top values for placement. This made it difficult to wrap filter values without having them collide with each other.
I contacted Ag-grid support and they confirmed that dynamic filter list widths are not supported. They did mention their tooltips feature though, which works for my use case.
I modified that example in two ways:
Only show tooltips for filter list values that are longer and will be cut off by the edge of the filter menu.
Only show tooltips for values in the filter list, not for rows in the grid.
Here's my version of a custom tooltip with the above modifications:
export class GridColumnFilterTooltip {
init(params) {
const FILTER_VALUE_CHARACTER_LIMIT = 28;
this.tooltip = document.createElement("div");
if (
params.location === "setFilterValue" &&
params.value.length > FILTER_VALUE_CHARACTER_LIMIT
) {
this.tooltip.classList.add("grid-column-filter-tooltip");
this.tooltip.innerHTML = params.value;
}
}
getGui() {
return this.tooltip;
}
}
I have this img element in my HTML project:
<img id="themeToggle" src="./images/moon.svg">
and i want to change the source of this element to be "./images/sun.svg".
I tried with:
void main() {
var themeToggleButton = querySelector('#themeToggle');
themeToggleButton?.onClick.listen((event) {
themeToggleButton.dataset['src'] = './images/sun.svg';
});
}
since the .dataset attribute is the only one that lets you to access the selected element's attributes, but it does not work. Any suggestion, please?
You should be able to use the .attributes getter to get the attributes Map and set there the value:
themeToggleButton?.attributes['src'] = './images/sun.svg'
Note: .dataset (as specified in the docs) is used only for the element properties that start with data-
I have defined my grid column as below,
WebGridColumn colRequestorEmail= new WebGridColumn();
colRequestorEmail.ColumnName = "RequestorEmail";
colRequestorEmail.Header = "Requestor Email Id";
colRequestorEmail.CanSort = true;
colRequestorEmail.Style = "name";
and my CSS as below,
.name { width: 0px;visibility: hidden; }
I am still able to see the column that I want to pass as hidden?
you add a css name here and set the actual attribute with your css file
// Summary:
// Gets or sets the CSS class attribute that is rendered as part of the HTML table
// cells that are associated with the System.Web.Helpers.WebGrid column.
//
// Returns:
// The CSS class attribute that is applied to cells that are associated with the
// column.
I'm trying to hide certain tags by using one ID element, but seem like it only hide the first tag with the ID element that I used.
DEMO : http://jsfiddle.net/mgm3j5cd/
How can i solve this issue? I wanted to hide the tag only with the ID element that I've declared. Appreciated for helps
You have this tagged as CSS, so the following CSS in your page's stylesheet will work:
#hide {
display: none;
}
Edit:
If you must only use JavaScript, you can do the following. Keep in mind that your document is already technically invalid by having multiple elements with the same ID, so this approach may not work in every browser. (I tested with Firefox 32).
Working JSFiddle: http://jsfiddle.net/88yw7LL9/2/
function hideByID(string) {
var element = document.getElementById(string); // get first matching element
var array = [];
while(element) {
array.push(element);
element.id = string + '-processed'; // change ID so next call gets the next matching element
element = document.getElementById(string);
}
for(var i = 0; i < array.length; i++) {
array[i].id = string; // revert ID to previous state
array[i].style.display="none"; // hide
}
}
hideByID('hide');
The simplest solution should be to assign 'class' attribute to certain elements you want to hide, like :
.XXXX
{
display:none;
}
Perhaps, you want to specify some elements hidden with id, like :
#id1 , #id2
{
display:none;
}
or
div#id1 , div#id2 //more accurate
{
display:none;
}
but, unfortunately, you can't hide elements you want by using one ID.
How can I make the drop down show all the content of one option when it is expanded? If an option in the drop down is, for instance, a whole sentence and select tag width is small, the user in IE will not be able to read whole option. This is not the case in Mozilla where the whole content is shown when drop down is expanded.
Is there any way to avoid this behavior in IE8,
Thanks
I had a similar constraint when working against IE8 and the oh so famous drop down list truncating. I have multiple drop down lists on my page, one after another, some inside top nav content, and IE8 decides to cut off my attribute option text properties. Now, like many of us, I don't want to set the width obscurely large, so this option is out of question.
After a lot of research, I couldn't find a great answer, so I went ahead and fixed it with jQuery and CSS:
First, let's make sure we are only passing our function in IE8:
var isIE8 = $.browser.version.substring(0, 2) === "8.";
if (isIE8) {
//fix me code
}
Then, to allow the select to expand outside of the content area, let's wrap our drop down lists in div's with the correct structure, if not already, and then call the helper function:
var isIE8 = $.browser.version.substring(0, 2) === "8.";
if (isIE8) {
$('select').wrap('<div class="wrapper" style="position:relative; display: inline-block; float: left;"></div>').css('position', 'absolute');
//helper function for fix
ddlFix();
}
Now onto the events. Since IE8 throws an event after focusing in for whatever reason, IE will close the widget after rendering when trying to expand. The work around will be to bind to 'focusin' and 'focusout' a class that will auto expand based on the longest option text. Then, to ensure a constant min-width that doesn't shrink past the default value, we can obtain the current select list width, and set it to the drop down list min-width property on the 'onchange' binding:
function ddlFix() {
var minWidth;
$('select')
.each(function () {
minWidth = $(this).width();
$(this).css('min-width', minWidth);
})
.bind('focusin', function () {
$(this).addClass('expand');
})
.change(function () {
$(this).css('width', minWidth);
})
.bind('focusout', function () {
$(this).removeClass('expand');
});
}
Lastly, make sure to add this class in the style sheet:
select:focus, select.expand {
width: auto;
}
