I am using jsPdf to export table data as pdf file, I have about 50 columns in my table.
but i am not able to see all columns in pdf. only few col are visible rest seems out of page, but there is no scrollbar in pdf file.
please suggest how to get a horizontal scrollbar on pdf page.
Below is my code snippet :
exportPDF(myTableHeaders,myTableData) {
const pdf = new jsPDF();
pdf.setFont("helvetica");
pdf.setFontSize(6);
;
let headerConfig = myTableHeaders.map((header) => ({
name: header.fieldName,
prompt: header.label,
width: 30,
align: "center",
fontSize: 6,
padding: 0,
}));
pdf.table(20, 30, myTableData, headerConfig);
pdf.save("pdf.pdf");
}
Below is snap :
I`m using Swiper with such params:
var mySwiper = new Swiper('.swiper-container', {
slidesPerView: 6,
spaceBetween: 15,
nextButton: '.swiper-button-next',
prevButton: '.swiper-button-prev'
});
Usual the width of items is ok (see image 1)
But sometimes the page is loaded with an item which width is 100% of the parent container width. (see image 2)
How can i fix it?
Is it possible to reverse a master timeline within GSAP? I know you can reverse a timeline that is not nested.
Here's the code:
// hide copy content divs
const hideCopyContentDivsTl = new TimelineMax()
hideCopyContentDivsTl.to(copyContentDivs, 1, {
height: 0,
width: 0,
autoAlpha: 0
})
// shrink copy wrapper div
const shrinkCopyWrapperTL = new TimelineMax()
shrinkCopyWrapperTL.to(copyWrapperDiv, 1, {
width: '2%',
height: '4%'
})
// fade remove bg and change to white
const fadeLargeBgImgTl = new TimelineMax()
fadeLargeBgImgTl.to(largeImage, 1, {
backgroundColor: "#fff"
})
// the master timeline to manage the parts
const masterTimeline = new TimelineMax({paused: true})
masterTimeline.add(hideCopyContentDivsTl)
.add(shrinkCopyWrapperTL)
.add(fadeLargeBgImgTl)
// assume that there is a mechanism to change the state of playVideo between true and false
if (this.state.playVideo === false) {
console.log("should play: ", masterTimeline)
masterTimeline.play()
} else {
console.log("should reverse: ", masterTimeline)
masterTimeline.reverse()
}
I can get it to play forwards, just not in reverse. Do I need to tell the browser where to start in the timeline so that it can play in reverse?
The problem is with my code and not with GSAP. I have new timelines created on every click. How will it reverse something that it doesn't have a previous reference to? The solution would be to create the timelines outside of the click event and then based on the state, play forward or reverse the animation.
I have buttons I want to center horizontally in a view. There are three, and all I can seem to get is:
[button1-button2-button3------------------------------]
What I really want is
[--------button1--------button2--------button3--------]
These buttons are dynamic widths too. The amount of buttons will change, some views have 1, others have 2 or 3. Depending on an action, the number of buttons can change. I need this support both iOS and android.
Try splitting the screen into n different columns using percentage layout. Then add your buttons to their respective invisible container.
var n = // Your number of buttons horizontal
var container = Ti.UI.createView({width : "100%", layout: "horizontal" });
for(var i=0;i<n;i++) {
var column = Ti.UI.createView({
width : (100/n)+"%",
});
// Create your button here
// .....
// .....
// Now add it to the column
column.add(yourNthButton);
// Now add the column to the container
container.add(column);
}
How about wrapping your buttons in a view with layout set to 'horizontal'?
var wrapperView = Ti.UI.createView({
layout : 'horizontal',
...
});
// In a view with horizontal layout,
// the positioning is relative to the preceding element
var buttonOne = Ti.UI.createButton({
right : 10,
...
});
wrapperView.add(buttonOne);
Untested, but give it a try!
UPDATE
Ok, the above code alone won't do what you wanted. I wrote a more complete example here.
Seems a bit clumsy, so if someone has a better solution, please let us know!
// Create our window
var win = Ti.UI.createWindow();
// Our wrapper view
var wrapperView = Ti.UI.createView({
width : Ti.UI.FILL,
height : 40,
top : 0,
layout : 'horizontal',
});
// Add some test buttons to our wrapper
for(var i=0; i<3; i++) {
wrapperView.add(Ti.UI.createButton({
title : 'Test ' + i,
height : 30,
}));
}
// Add wrapperView to our window and open it
win.add(wrapperView);
win.open();
// Wait until "size" becomes available
win.addEventListener('postlayout', distributeButtons);
// Distribute buttons evenly
function distributeButtons() {
if(wrapperView.children) {
// Get the width of the wrapper view
var wrapperWidth = wrapperView.size.width;
var buttonWidths = 0;
var buttonSpacer;
var childrenLength = wrapperView.children.length;
// Get the button sizes
for(var i=0; i<childrenLength; i++) {
buttonWidths += wrapperView.children[i].size.width;
};
// Calculate the spaces between the buttons
buttonSpacer = (wrapperWidth - buttonWidths) / (childrenLength + 2);
// Set the buttons left value
for(var i=0; i<childrenLength; i++) {
wrapperView.children[i].left = buttonSpacer;
};
}
}
If you can put a toolbar, you can use the "flexspace" button, which will create a space necessary to fill the gap between other buttons. Here's the syntax from simple toolbar example in titanium docs:
var send = Titanium.UI.createButton({
title: 'Send',
style: Titanium.UI.iPhone.SystemButtonStyle.DONE,
});
var camera = Titanium.UI.createButton({
systemButton: Titanium.UI.iPhone.SystemButton.CAMERA,
});
var cancel = Titanium.UI.createButton({
systemButton: Titanium.UI.iPhone.SystemButton.CANCEL
});
flexSpace = Titanium.UI.createButton({
systemButton:Titanium.UI.iPhone.SystemButton.FLEXIBLE_SPACE
});
var toolbar = Titanium.UI.iOS.createToolbar({
items:[send, flexSpace, camera, flexSpace, cancel],
bottom:0,
borderTop:true,
borderBottom:false
});
win.add(toolbar)
try this
var yourView = Ti.UI.createView({ layout:"horizontal"});
var buttonsHolder = Ti.UI.createView({ width:"100%" });
// this view will hold the buttons
var button1 = Ti.UI.createButton({title:"button1 , left:0"}); // the left button
var button2 = Ti.UI.createButton({title:"button2"}); // the middle button
var button3 = Ti.UI.createButton({title:"button3",right:0}); // the right button
buttonsHolder(button1);
buttonsHolder(button2);
buttonsHolder(button3);
yourView.add(buttonsHolder);
Hieyy bro
If you are want achieve this using titanium alloy in xml. in that case you can use %.
Container ------------width 100%-----layout horizontal---------
first child--------left 10%------- width 20%
second child--------left 10%------- width 20%
third child--------left 10%------- width 20%-----right 10%
if you don't get your answer please let me know
Spartacus Thanks:)
If using Alloy, then I recommend using percentages to control width and position. Here's an example that centers three small images below a larger image, also centered:
<TableViewRow selectionStyle="Ti.UI.iPhone.TableViewCellSelectionStyle.NONE" backgroundColor="white" layout="vertical">
<ImageView id="detailsFeaturedImage" top="10"/>
<View height="60">
<View layout="horizontal">
<View left="25%" width="10%"><ImageView image="images/thumb-up-7#2x.png" onClick="thumb_up" /></View>
<View left="10%" width="10%"><ImageView image="images/thumb-down-7#2x.png" onClick="thumb_down"/></View>
<View left="10%" width="10%"><ImageView image="images/flag-7#2x.png" onClick="flag_for_review"/></View>
</View>
</View>
</TableViewRow>
I need my jquery to vertically center a div on Document ready and also if there is a resize of browser but I'm having difficulty combining the 2 scripts. You can see below that I have to call it twice to get it to work in both instances. I'm sure there is a better way to write this but I am a little unsure of how to do it clean.
$(document).ready(function() {
if ($(window).width() >= 770){
var $el = $('#main');
$el.css('position', 'absolute').css({
left: ($(window).width() - $el.width()) / 2,
top: ($(window).height() - $el.height()) / 2
});
}
$(window).resize(function(){
if ($(window).width() >= 770){
var $el = $('#main');
$el.css('position', 'absolute').css({
left: ($(window).width() - $el.width()) / 2,
top: ($(window).height() - $el.height()) / 2
});
}
});
