This article illustrates jQuery's method of automatically resizing fonts. Share to everybody for everybody reference. The specific analysis is as follows:
An jQuery function is used here to automatically change the font size of the text in the element.
$.fn.fontfit = function(max) {
var max_size = 18;
if (typeof(max) == "undefined")
max = max_size;
$(this).wrapInner('<div id="fontfit"></div>');
var dheight = $(this).height();
var cheight = $("#fontfit").height();
var fsize = (($(this).css("font-size")).slice(0,-2))*1;
while(cheight<dheight && fsize<max) {
fsize+=1;
$(this).css("font-size",fsize+"px");
cheight = $("#fontfit").height();
}
while(cheight>dheight || fsize>max) {
fsize-=1;
$(this).css("font-size",fsize+"px");
cheight = $("#fontfit").height();
}
$("#fontfit").replaceWith($("#fontfit").html());
return this;
}
