Je cherche à redimensionner automatiquement la police pour chaque nouvelle ligne de largeur égale pour un champ de texte modifiable multiligne. S'il vous plaît vérifier l'URL ci-dessous:Redimensionner automatiquement le champ de texte modifiable multiligne dans Jquery
http://api.pstr.co/html/template/003_script
En ce moment, la taille de la police est comme ça
et je veux être comme ça:
Le code jquery pour ce plugin est le suivant:
function getBaseFontSize(){
var baseFontSize = Math.round(0.15*Math.min($(window).width(), $(window).height()));
return baseFontSize;
}
function editModeSetup(){
var contentBlock = $(".content");
var container = $(".block");
var scalableText = $(".scalable");
$('[contenteditable]').each(function (index) {
var $this = $(this);
$this
.on("keydown", function(){
clearTimeout($this.timeout);
fitTextMultiline(scalableText,contentBlock,container);
//if (!$this.hasClass("edited")) $(this).addClass("edited");
}).on("focus", function() {
//if (!$this.hasClass("edited")){
$this.selectText();
//}
// Work around Chrome's little problem
$this.mouseup(function() {
// Prevent further mouseup intervention
$this.unbind("mouseup");
return false;
});
}).on("keyup", function() {
$this.timeout = setTimeout(function(){ fitTextMultiline(scalableText,contentBlock,container); }, 400);
});
//$(".content").css("font-size", getBaseFontSize());
$("html").css("font-size", getBaseFontSize());
});
fitTextMultiline(scalableText,contentBlock,container);
$(window).resize(function() {
fitTextMultiline(scalableText,contentBlock,container);
});
var myWidth = window.innerWidth;
var myHeight = window.innerHeight;
ga('send',
'event',
'Viewport',
'Size',
myWidth+'x'+myHeight,
{'nonInteraction': 1});
}
function fitTextMultiline(scalableText, contentBlock, container) {
// startvwith small type and push the size up? to make sure more fits on one line...
var maxHeight = container.height();
var maxWidth = container.width();
//console.log(".\n")
//console.log(scalableText.text())
var fontSize = 7*getBaseFontSize(); // 20;
var fontUnits = "px"; // "vmin";
do {
scalableText.css('font-size', fontSize+fontUnits);
contentHeight = contentBlock.height();
contentWidth = contentBlock.width();
//console.log("--- " + fontSize +" ---")
//console.log(contentHeight + " ? " + maxHeight)
//console.log(contentWidth + " ? " + maxWidth)
fontSize = Math.round(fontSize - fontSize*0.1);
} while ((contentHeight > maxHeight || contentWidth > maxWidth ) && fontSize > 10);
//+ fontSize/2
