按ID选择jQuery自动完成值

时间:2013-09-07 09:32:47

标签: javascript jquery jquery-autocomplete

我有2个带有jquery自动完成功能的文本框。我的要求是

如果我选择Text Box 1标签或值aa且其ID为1,则在Text Box 2标签或值中包含ID为1的{​​{1}}应该选择(aa1)

我不想将Text Box 1中的值或匹配值复制到Text Box 2,反之亦然。

我也想知道how to select autocomplete value by passing its id?

示例:

如果我在文本框1中选择bb(id = 2),则应选择文本框2中的bb1(id = 2)。

如果我在文本框2中选择cab1(id = 5),则应选择文本框1中的cab(id = 5)。

要按ID选择自动填充值,您必须使用value代替标签:

例如:

        $("#txt2").autocomplete({
            source: arraytxt2,
            minLength: 1,
            select: function(event, ui) {
              $("#txt1").val(ui.item.value);  //selecting by its id(value)
            }
        });
