jQueryUI的自动完成极限多种选择

本文介绍了jQueryUI的自动完成极限多种选择的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我使用jQuery UI的自动完成,我试图限制多个结果。基本上我建我使用的是自动完成的调遣PM系统。但我试图限制人们单个邮件可以发送到的金额。所以像限制最多选择25。

有什么办法来限制呢?他们已经达到最大的视觉指示器还什么想法?

 选择:函数(事件,UI){
    VAR而言=拆分(THIS.VALUE);
    如果(terms.length&下; = 2)
    {
        //删除当前输入
        terms.pop();
        //添加所选项目
        terms.push(ui.​​item.value);
        //添加占位符来获得在最后逗号和空格
        terms.push();
        THIS.VALUE = terms.join(,);
        返回false;
    }
    其他
    {
        $(本).effect(亮点,{},1000);
        $(本).addClass(红);
        $(#警告)HTML(<跨度风格=颜色:红色;'>最多达人< / SPAN>中)。
        返回false;
    }
}


解决方案

这可以很容易地真正聆听的的。您可以通过并去除类自动完成制作,例如红色。我想你可以用这样的一点点努力完成自己。

 选择:函数(事件,UI){
    VAR而言=拆分(THIS.VALUE);
    如果(terms.length&下; = 2){
        //删除当前输入
        terms.pop();
        //添加所选项目
        terms.push(ui.​​item.value);
        //添加占位符来获得在最后逗号和空格
        terms.push();
        THIS.VALUE = terms.join(,);
        返回false;
    }其他{
        VAR最后= terms.pop();
        $(本).VAL(this.value.substr(0,this.value.length - last.length - 2)); //将删除输入文本
        $(本).effect(亮点,{},1000);
        $(本).addClass(红);
        $(#警告)HTML(<跨度风格=颜色:红色;'>最多达人< / SPAN>中)。
        返回false;
    }
}

I am using the jQuery UI autocomplete and I am attempting to limit the multiple results. Basically I'm building a PM system I am using the autocomplete for the to field. But I'm trying to limit the amount of people a single message can be sent to. So like limit the max selections to 25.

Is there any way to limit this? Also any ideas on a visual indicator that they have reached the max?

 select: function( event, ui){
    var terms = split( this.value );
    if(terms.length <= 2)
    {
        // remove the current input
        terms.pop();
        // add the selected item
        terms.push( ui.item.value );
        // add placeholder to get the comma-and-space at the end
        terms.push( "" );
        this.value = terms.join( ", " );
        return false;
    }
    else
    {
        $(this).effect("highlight", {}, 1000);
        $(this).addClass("red");
        $("#warnings").html("<span style='color:red;'>Max people reached</span>");
        return false;
    }
}
解决方案

That can be achieved real easily by listening events. You could make the color red for example by adding class and removing class to autocomplete. I think you can accomplish this yourself with a little bit of effort.

select: function( event, ui ) {
    var terms = split( this.value );
    if(terms.length <= 2) {
        // remove the current input
        terms.pop();
        // add the selected item
        terms.push( ui.item.value );
        // add placeholder to get the comma-and-space at the end
        terms.push( "" );
        this.value = terms.join( ", " );
        return false;
    } else {
        var last = terms.pop();
        $(this).val(this.value.substr(0, this.value.length - last.length - 2)); // removes text from input
        $(this).effect("highlight", {}, 1000);
        $(this).addClass("red");
        $("#warnings").html("<span style='color:red;'>Max people reached</span>");
        return false;
    }
}

P.S I also think one of these plugins could be suitable thanks to google:
