我们如何使自定义广播和复选框可调整大小？

Question

我创建了一个自定义复选框，但是使用jquery使其可调整大小时出错？

＆＃13;

＆＃13;

$(document).ready(function() {
  $('.squaredFour').resizable({});
});

＆＃13;

.squaredFour {
	display: none;
}
.squaredFour {
	width: 20px;	
	margin: 20px auto;
	position: relative;
}

.label {
	cursor: pointer;
	position: absolute;
	width: 20px;
	height: 20px;
	top: 0;
	border-radius: 4px;

	-webkit-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	-moz-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	background: #fcfff4;

	background: linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
	filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fcfff4', endColorstr='#b3bead',GradientType=0 );
}

.label:after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
	filter: alpha(opacity=0);
	opacity: 0;
	content: '';
	position: absolute;
	width: 9px;
	height: 5px;
	background: transparent;
	top: 4px;
	left: 4px;
	border: 3px solid #333;
	border-top: none;
	border-right: none;

	-webkit-transform: rotate(-45deg);
	-moz-transform: rotate(-45deg);
	-o-transform: rotate(-45deg);
	-ms-transform: rotate(-45deg);
	transform: rotate(-45deg);
}

.label:hover::after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
	filter: alpha(opacity=30);
	opacity: 0.5;
}

.squaredFour:checked + label:after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
	filter: alpha(opacity=100);
	opacity: 1;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<input type="checkbox" value="None" id="squaredFour" name="check" class="squaredFour" />
<label for="squaredFour" class="label"></label>

Answer 1

您需要在代码中包含jquery UI以使用可调整大小的函数，并确保在此之前包含jquery。它现在有效

＆＃13;

＆＃13;

$(document).ready(function() {
  $('.squaredFour').resizable({});
});

＆＃13;

.squaredFour {
	display: none;
}
.squaredFour {
	width: 20px;	
	margin: 20px auto;
	position: relative;
}

.label {
	cursor: pointer;
	position: absolute;
	width: 20px;
	height: 20px;
	top: 0;
	border-radius: 4px;

	-webkit-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	-moz-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
	background: #fcfff4;

	background: linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
	filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fcfff4', endColorstr='#b3bead',GradientType=0 );
}

.label:after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
	filter: alpha(opacity=0);
	opacity: 0;
	content: '';
	position: absolute;
	width: 9px;
	height: 5px;
	background: transparent;
	top: 4px;
	left: 4px;
	border: 3px solid #333;
	border-top: none;
	border-right: none;

	-webkit-transform: rotate(-45deg);
	-moz-transform: rotate(-45deg);
	-o-transform: rotate(-45deg);
	-ms-transform: rotate(-45deg);
	transform: rotate(-45deg);
}

.label:hover::after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
	filter: alpha(opacity=30);
	opacity: 0.5;
}

.squaredFour:checked + label:after {
	-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
	filter: alpha(opacity=100);
	opacity: 1;
}

你不需要使用JQuery。你可以在图片

的帮助下使用 CSS 来实现它

#squaredFour
{ 
    float: left; 
    width: 200px; 
    height: 200px;
    background : url("pathofimage/check.png");
}
