最后,我突然不得不调试一些 jQuery 。 这并不是我的专业领域。 当前脚本正在寻找一个由 jQuery 提供的文本框中的值, 而该文本框是 JQuery 提供的, 失败了 。
查看铬中的 DOM 时, 我可以看到此元素在下面有一个“ 来源日期” 元素。 变量浏览器将此元素列为类型 jQuery. fn.jQuery.init[1] 。 它包含元素 0: HTML InputEplement, 上下文: HTMLDocument, 长度:1 和一些其它东西 。
值 I m 之后的值在 0 对象中, 但我似乎找不到要找到的语法 。 只要我能将jQuery 构建事物的语法作为数组来表示, 但只能做 < code> 。 从Date[0] 或 开始。 从Date(0) 或 开始。 从Date.0 全部 产生错误, “ 对象目录的属性不是函数 ” 。
我如何得到我的价值?
您的变量是一个 jQuery 对象 。
进入其中所含(第一次和唯一一次)DOM单元,使用:
myObject[0]
或
myObject.get(0)
如果您只想获得 HTMLInputEplement 的值, 您可以使用 :
myObject.val()
