我有一个自动填充文本框,需要响应2个事件:
focusout假设用户完成输入时.因此,如果用户选中文本框,则表示用户已完成输入.)select事件来确定)问题:
当用户选择自动完成值列表中的项目时,事件链focusout首先被调用,然后是select.在进入时focusout,我只能访问用户键入的内容,而不是用户选择的自动完成值列表 - 这就是我实际需要的内容.我该如何解决这个问题?
重现问题的步骤:
aActionScript从自动完成值列表中选择观察console.debug消息:

这是代码:

这正是jQueryUI为以下内容引入特殊change事件的原因autocomplete:
如果字段模糊,则触发,如果值已更改; ui.item指的是所选项目.
此活动可以满足您的两个要求:
$("#1").autocomplete({
/* snip */
change: function(event, ui) {
if (ui.item) {
console.log("ui.item.value: " + ui.item.value);
} else {
console.log("ui.item.value is null");
}
console.log("this.value: " + this.value);
}
});

ui.item 当用户未从自动填充候选列表中选择值时,将不会定义. this.value将永远是正确的.这是一个例子:http://jsfiddle.net/33GJb/
