AutoHeightTextArea() {
$.fn.autoHeight = function() {
function autoHeight(elem) {
var height = $('#height').height()
console.log(height)
elem.style.height = height + 'px'
if(elem.scrollHeight > 0){
// elem.style.height = 'auto';
elem.scrollTop = 0; //防抖动
elem.style.height = elem.scrollHeight + 'px';
}
}
this.each(function() {
autoHeight(this);
$(this).on('keyup', function() {
autoHeight(this);
});
});
}
$('textarea[autoHeight]').autoHeight();
}
在 textarea标签上增加属性 autoHeight = “true” 即可。
