我有4张图片,用户只能选择4张图片中的1张。
当用户点击任何图片时,应该停用所点击的图片以及其他3张图片,同一位用户必须再次点击“点击”图片。图像以启用图像。
基本上我需要让图像看起来像它的Clickable(有一些边框或什么......),然后点击图像说' A'用户获得一条消息(如when_i_click_carrom()所示),所有图像(B,C,D)应该被禁用(仅限该用户),同一用户必须点击禁用的图像'甲'启用它。
注意:对于当前用户和其他用户,只应禁用图像A,但其他用户可以点击其他图像B,C,D,直到当前用户启用图像A
...
<script>
var when_i_click_carrom = function(){
alert('You selected Carrom!');
}
</script>
...
<div class="container">
<div class="grid_layout_row">
<div class="col-md-6">
<div class="sidebar"><img src="images/carrom.jpg" alt="carrom" class="img-responsive" onclick="when_i_click_carrom();"/></div>

尝试使用querySelectorAll
。我没有默认的禁用属性。请尝试使用类
document.querySelectorAll('.img-responsive').forEach(function(a) {
a.addEventListener('click', function() {
this.disabled = this.disabled == true ? false : true;
this.classList.toggle('disable')
//console.log(this.disabled)
})
})
&#13;
.disable {
opacity: 0.5;
}

由于您使用的是bootstrap,因此当您点击其中一个项目时,您可以使用图像按钮并对所有项目使用禁用类。我创建了一个例子:
HTML:
<img *ngIf="!isImgLoaded" src="assets/images/profileimage.png" >
<img [hidden]="!isImgLoaded" [src]="user.image" (load)="isImgLoaded = true" >
脚本(使用Jquery):
<div class="container">
<div class="grid_layout_row">
<div class="col-md-6">
<div class="sidebar"><button type="button" id="btn1" class="btn btn-primary myBtn" onclick="imgClicked()">
<img src="http://lorempixel.com/400/200/sports/1" alt="carrom" class="img-responsive">
</button></div>
</div>
<div class="col-md-6">
<div class="sidebar"><button type="button" id="btn2" class="btn btn-primary myBtn" onclick="imgClicked()" >
<img src="http://lorempixel.com/400/200/sports/2" alt="carrom" class="img-responsive">
</button></div>
</div>
<div class="col-md-6">
<div class="sidebar"><button type="button" id="btn3" class="btn btn-primary myBtn" onclick="imgClicked()">
<img src="http://lorempixel.com/400/200/sports/3" alt="carrom" class="img-responsive">
</button></div>
</div>
<div class="col-md-6">
<div class="sidebar"><button type="button" id="btn4" class="btn btn-primary myBtn" onclick="imgClicked()">
<img src="http://lorempixel.com/400/200/sports/5" alt="carrom" class="img-responsive">
</button></div>
</div>
