I use InnovaEditor to create edit block.
I try to find way in order to set dynamic height of edit block.
Ie block height should correspond block content.
HTML:
<iframe id="idContenteditor_field_1" name="idContenteditor_field_1" style="width:100%;height:100%;border:none;">
<html>
<head></head>
<body>12345</body>
</html>
</iframe>
What I did:
1) set keyup event in iframe body
2) wrap to content to get real height
3) set calculated height to the iframe
Javascript:
var $iframe = $("iframe#idContenteditor_field_1");
var $iframeBody = $iframe.contents().find("body");
$iframeBody.keyup(function(e) {
if ($(this).find('.content').length === 0) {
// add wrap
var bodyContent = $(this).html();
$(this).html('<div class="content">' + bodyContent + '</div>');
}
var $contentBlock = $(this).find('.content');
var bodyHeight = $contentBlock.outerHeight();
$('#idContenteditor_field_1').height(bodyHeight); // set real height
});
It works fine.
The issue:
I have 10 edit blocks on the page and they are same except id.
But I have problems when I try to apply this code to all iframes.
// return all iframes
var $iframes = $('iframe[id^="idContenteditor_field_"]');
// return only single body of first iframe.
var $iframesBody = $iframes .contents().find("body");
So I can't set keyup event for all iframes.
Could you help me?
Maybe there is easier way to set dynamic height?
var $iframesBody = $iframes .contents().find("body");
^^^ it returns only single body of first iframe, because rest iframes have not yet been loaded fully.
So I just execute this script after load of all iframes.
And it works.
I haven't tested this code, but something like below should work.
You just need to iterate through your objects and set the event listener for each one in turn.
var $iframes = $('iframe[id^="idContenteditor_field_"]');
$iframes.each(function(index, item) {
var $iframeBody = $(item).contents().find("body");
$iframeBody.keyup(function(e) {
if ($(this).find('.content').length === 0) {
// add wrap
var bodyContent = $(this).html();
$(this).html('<div class="content">' + bodyContent + '</div>');
}
var $contentBlock = $(this).find('.content');
var bodyHeight = $contentBlock.outerHeight();
$(item).height(bodyHeight); // set real height
});
});

I'am trying to identify with javascript if I need to force a page break in my document.
One element that is overflow hidden. I loop through each of the elements within this document. I remove all last childs until the height of the element within the overflow:hidden element is smaller. Now I know, when to page break and I push all removed childs in the new page.
Works fine in browser. But not in PDF...
I'am using http://wkhtmltopdf.org/
See problem here: Left: PDF, Right: Browser (Chrome)
Height of 3262px vs 358px...
Same if I use .clientHeight or jQuery .height().
Does anyone know a workaround to get heights the same?
Some code:
function isOverflowed(element){
// return element.scrollHeight > element.clientHeight;
// console.log(element.clientHeight);
// console.log(element.parent().height() +'>'+ element.height());
return element.parent().height() < element.height();
}
// var daysWrapper = document.getElementById('days');
// var days = daysWrapper.querySelectorAll(".section.day");
var days = $('#days .section.day');
// console.log(days);
days.each(function() {
var $this = $(this);
var area = $this.find('.day-info');
var content = area.children();
var lasts = $( '<div class="lasts">' );
var test = 0;
while(isOverflowed(content)) {
var last = content.children().last();
// lasts.append( $( last ) );
last.clone().prependTo(lasts);
last.remove();
test++;
if (test > 6) break;
}
content.find('h1').html(area.height() + ' - ' + content.height());
if (lasts.children().length ) {
var newPage = $this.clone();
newPage.insertAfter($this);
newPage.find('.day-image').remove();
newPage.find('.day-info').removeClass('overflow');
newPage.find('.day-info').children().html(lasts.html());
}
});
Thanks!
I'm using jscript to load a string in to several elements of an array, then display the useful element in html.
There's a pulldown menu that causes the string to change. So, I need the function to be re-run when that happens.
I have been able to successfully display the element using window.onload
and, I have been able to successfully display the element AFTER the pulldown menu has been changed.
But, I can't seem to display the element with window.onload and subsequently after item.onchage
If anyone has any suggestions, I'd be grateful.
Here is the code that works for window.onload
window.onload = function() {
var selectedOptionId = jQuery('select').val();
var optionPartNumber = jQuery('input[name="OptID_' + selectedOptionId + '"]').val();
//loads the string in to an array and returns the 2nd element
var optionPartNumber = optionPartNumber.split(".")[1];
document.getElementById("MASNUM").innerHTML=optionPartNumber;
}
Here is the code that works for pulldown.onchange
jQuery(function(){
jQuery('.dropdownimage-format select').on('change', function(){
var selectedOptionId = jQuery('select').val();
var optionPartNumber = jQuery('input[name="OptID_' + selectedOptionId + '"]').val();
var optionPartNumber = optionPartNumber.split(".")[1];
document.getElementById("MASNUM").innerHTML=optionPartNumber;
});
In both cases, the element is displayed in html by
<a id="MASNUM">
I would like to implement a Table of Contents in the sidebar of a Google Docs document which will take you to the appropriate sections when clicked. I am generating the HTML for the sidebar element by element, and I see that there is a moveCursor(position) function in Document class, but I can't see how to actually call it using onclick. Not the full code but shows the problem:
function generateHtml() {
var html = HtmlService.createHtmlOutput('<html><body>');
var document = DocumentApp.getActiveDocument();
var body = document.getBody();
//Iterate each document element
var totalElements = body.getNumChildren();
for(var i = 0; i < totalElements; ++i) {
var element = body.getChild(i);
if(element.getType() == DocumentApp.ElementType.PARAGRAPH) {
var text = paragraph.getText();
if(text.trim()) { //Not blank paragraph
var position = document.newPosition(element, 0);
/**Would like to have <a onclick=document.moveCursor(position)> here**/
//Show first 20 chars as preview in table of contents
html.append('Detected paragraph ')
.append(text.substring(0, 20))
.append('<br />');
}
}
}
html.append('</body></html>');
return html;
}
How can I accomplish this in Apps Script? The code can be completely restructured as needed.
This line:
/**Would like to have <a onclick=document.moveCursor(position)> here**/
Change to:
<div onmouseup="myClientFunction()">Text Here</div>
Add a <script> tag to your HTML:
<script>
var valueToSend = code to get value;
window.myClientFunction = function() {
google.script.run
.myGsFunctionToMoveCursor(valueToSend);
};
</script>
Then you need a myGsFunctionToMoveCursor() function in a script file (.gs extension)
function myGsFunctionToMoveCursor(valueReceived) {
//To Do - Write code to move cursor in Google Doc
. . . Code to move cursor
};
I have a form with a print function. Inside the function I open a window, build the document, add the head with style sheets, add the form HTML and make the call to print the last part of the body. The problem is the initial print preview/print doesn't reflect the style. If I cancel the print and attempt to print manually, the style shows up.
I've tried quite a few ways of doing this with no luck. It seems like a timing issue. Any ideas?
Browser is Chrome. Below is the JS function. (This is injected with a faces context).
function printForm(windowTitle, path){
var printWindow = window.open();
var printDocument = printWindow.document;
var headHtml = "<link href='" + path + "/css/style.css' rel='stylesheet' type='text/css'/>";
printDocument.getElementsByTagName('head')[0].innerHTML = headHtml;
var printDiv = printDocument.createElement("DIV");
var formDiv = document.getElementById("formDiv");
printDiv.innerHTML = formDiv.innerHTML // Styling here is the issue
printDocument.body.appendChild(printDiv);
var scriptTag = printDocument.createElement("script");
var script = printDocument.createTextNode("print();");
scriptTag.appendChild(script);
printDocument.body.appendChild(scriptTag);
}
I think you need a setTimeout to delay printing for a second or two so the style can be applied. You'll need to tinker to find the right length.
Instead of trying to guessing with a timer, it might be more precise to use the load event on the <link ...> to know exactly when it has completed loading.
Below is a function I use which illustrates this technique. It uses an off-screen <iframe> to print a portion of a page. It's jQuery based, but the principles are the same in vanilla JS. Note the setting of the <link>'s onload function with an anonymous function which invokes print() on the <iframe>'s window object.
/*
* expects:
* <tag id="whatever">...goop...</tag>
* <input type="button" class="printit" data-target="whatever" value="Print">
*/
$(function() {
$( '.printit' ).click(function() {
var goop = $( '#' + this.dataset.target ).prop('outerHTML');
var ifr = $('<iframe>');
var bas = $('<base href="' + document.baseURI + '">');
var lnk = $('<link rel="stylesheet" href="/css/print.css">');
lnk.on('load', function() { /* CSS is ready! */
ifr[0].contentWindow.print();
});
ifr.css( { position: 'absolute', top: '-10000px' } )
.appendTo('body')
.contents().find('body').append(goop);
ifr.contents().find('head').append(bas).append(lnk);
return false;
});
});
I am trying to get the width property from one element and assign to another.
Here's my code (that does not work):
window.onload=function() {
var morphWidth = document.getElementById('morph').width();
var scrollbar = document.getElementById('scrollbar');
scrollbar.style.width = morphWidth + "px";
}
You can get the element width:
document.getElementById("morp").style.width;
and you can set the element width:
document.getElementById("morph").style.width="300px";
Okay, so I tried this and that and finally found a solution:
$(function() {
var morphWidth = $('#morph').width();
var scrollbar = $('#scrollbar');
$('#scrollbar').css('width', morphWidth + 'px');
});
However, I don't have a clue why this works now. Let me know if you do!
If you use jQuery, then you can code like this:
var morphWidth = $('#morph').width();
If you use original Javascript, the you can code like this:
var morphWidth = document.getElementById('morph').offsetWidth;
jQuery object is different from DOM (Document Object Model).
The var scrollbar as same as.
