连续 Unbind/Bind 点击

Question

我有 5 个 div 类 (button1, button2, button3, button4, button5)

我想要的是所有类都不可点击 onload（button1 除外），然后在点击 button1 后，button2 处于活动状态，其他按钮不活动，依此类推。

所以按顺序点击。

HTML

<map name="Map" id="Map"> 
  <area id="button" title="HAT" alt="HAT" href="#" shape="poly" coords="xxx,xxx" /> 
  <area id="button2" title="SUN CREAM" alt="SUN CREAM" href="#" shape="poly" coords="xxx,xxx" /> 
</map>

我试过了：

$(function(){ $("#button2").unbind("click"); });

作为初始函数，然后在button1下点击函数：

$("#button1").click(function() { 
$("#Map #button2").bind("click");
});

这是因为它不允许点击 button2，但即使点击了 button1 仍然无法点击。

有什么想法吗？

Answer 1

你必须这样做 Document

$(document).ready(function(){
    $(".btn").unbind("click",function(){
      alert("unbind click");
    });
  
});

function btnClick(thisObj){
    //unbind all not current
     $(".btn").not(thisObj).unbind("click");
     //bind next btn
     $(thisObj).next().bind("click",function(){
      alert("bind click");
    });
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="button" class="btn" name="btn1" value="1" onclick="btnClick(this);">
<input type="button" class="btn" name="btn2"  value="2"  onclick="btnClick(this);">
<input type="button" class="btn" name="btn3"  value="3"  onclick="btnClick(this);">
<input type="button" class="btn" name="btn4"  value="4"  onclick="btnClick(this);">
<input type="button" class="btn" name="btn5"  value="5"  onclick="btnClick(this);">

试试这个：您可以禁用单击按钮并启用下一步按钮，请参见下面的代码

$(document).ready(function(){
    $('#Map').find('area').not('#button').attr('disabled',true);
    $('#Map area').on("click",function(){
        $(this).attr('disabled',true);
        $(this).next('area').removeAttr('disabled');
    }); 
});

在更通用和建设性的方法中，实施 jQuery 插件：

$("#button1").sequence("click")
    .handle(function () {
        alert("YOU...")
    })
    .handleNext("#button2", function () {
        alert("SHALL...")
    })
    .handleNext("#button3", function () {
        if (prompt("NOT PASS!!!") != "I'm Frodo, drunkie!") {
            alert("BZZZZZZZT!");
            return this.runBackward();
        }
        alert("Ah, oh, okaay...");
    })
    .handleNext("#button4", function () {
        alert("Pwned! ]:-}");
        this.resetSequence();
    });

$(function () {
    $("#button1").sequence("click")
        .handle(function () {
            alert("YOU...")
        })
        .handleNext("#button2", function () {
            alert("SHALL...")
        })
        .handleNext("#button3", function () {
            if (prompt("NOT PASS!!!") != "I'm Frodo, drunkie!") {
                alert("BZZZZZZZT!");
                return this.runBackward();
            }
            alert("Ah, oh, okaay...");
        })
        .handleNext("#button4", function () {
            alert("Pwned! ]:-}");
            this.resetSequence();
        });

});

(function ($) {
    $.fn.sequence = function (event) {
        this.sequencer = {
            event: event,
            plugged: this,
            disable : function (element, enable) {
                $(element).attr("disabled", (enable !== false) ? "disabled" : false);

            disablePrev: function (enable) {
                if (this.prevInSequence)
                    this.disable(this.prevInSequence, enable);
            },
            disableNext: function (enable) {
                if (this.nextInSequence)
                    this.disable(this.nextInSequence, enable);
            },
            hasPrev : function (prev) {
                this.prevInSequence = prev;
            },
            hasNext : function (next) {
                this.nextInSequence = next;
                this.plugged.resetSequence();
            },
            process : function (callback, event) {

                this.disable(this.plugged);
                this.disableNext(false);
            },
            reset: function () {

                if (this.nextInSequence)
                    this.nextInSequence.sequencer.reset();

        this.resetSequence = function () {

        this.handleNext = function (selector, callback) {
