有一段时间,我一直试图找到一种方法,以一种有吸引力的方式根据其内容设置<div>
的宽度。我希望能够告诉<div>
每隔一段时间换一次换行符,根据段落中有多少单词。所以例如,如果它是一个300字的长段,则宽度为500px并分割为多行,但如果它是10个字,则它只有100px宽,并且分成两个?
我并不急需它,但我放弃了谷歌搜索,如果周围的人有任何想法,我很好奇。

也许你可以使用这个小脚本(垂直移动鼠标)。它最初是在很久以前用ActionScript2编写的。
/*
outerNode : block element with a helper wrapper element inside
Fiddles with the width of outerNode until it reaches desired height (maxH)
Width is limited between minW and maxW
*/
var fitToHeight = function( outerNode, minW, maxW, maxH ){
var L,H,A; // Lo,Hi,Actual width for binary search
var $set = $(outerNode); // new width will be applied to the outer node
var $get = $($set).children(); // actual width / height readout
// Set initial width to the longest non-wrapping word (
$set.width( minW );
L = H = Math.min( maxW, Math.max( minW, $get.width())); // longest word
// grow the width until height falls below maxH
while( $get.height() > maxH && H < maxW ){
// remember the width of the last too high box: it will be the lower limit for bin.search
L = H;
H = Math.min( H*2, maxW ); // limited grow of upper limit
$set.width( H );
}
H = Math.min( maxW, $get.width() );
// binary search for the ideal width where height just falls below maxH
do{
A = Math.round( ( H + L )/2 );
$set.width( A );
if( $get.height() > maxH ) L=A; else H=A;
}while( H - L > 1 );
// width might be smaller by a subpixel, so increment it to guarantee maximum height
if( $get.height() > maxH )
$set.width( A+1 );
// set block's height if necessary
$set.height( maxH );
};
jQuery.fn.fitToHeight = function( minW, maxW, maxH ){
this.each(function(){
fitToHeight( this, minW, maxW, maxH );
});
}
