我设法使我的textarea字段在输入时增加和缩小。但是,如果您这里的内容已经超过一行,那么它不会自动加载为多行。
有什么想法吗?或提示?谢谢
$(document)
.on('focus.autoExpand', 'textarea.autoExpand', 'change.autoExpand', function(){
var savedValue = this.value;
this.value = '';
this.baseScrollHeight = this.scrollHeight;
this.value = savedValue;
})
.on('input.autoExpand', 'textarea.autoExpand', 'change.autoExpand', function(){
var minRows = this.getAttribute('data-min-rows')|0, rows;
this.rows = minRows;
rows = Math.ceil((this.scrollHeight - this.baseScrollHeight) / 16);
this.rows = minRows + rows;
});
