jquery设置input不可编辑,背景变灰,鼠标变禁止
先看效果
$("#id").attr("onfocus", "this.blur()"); $("#id").css("background", "#CCCCCC"); $("#id").css("cursor", "not-allowed");
不可编辑有三个方法
第一种是onfocus=this.blur(),这种比下面两种好,因为连文字也不能选择
$("#newNoteName").attr("onfocus", "this.blur()");
第二种是disabled="disabled"
$("#id").attr("disabled", "disabled");
第三种是readonly或者是readonly=“true”
$("#id").attr("readonly", "true");
亲测实例
js
//当变更类型选择汇款的时候收据编号是必填项,其他时收据编号置灰切不可编辑 function zhihui(type) { if(type==1){ $("#receiptNo").css("background", "#CCCCCC"); $("#receiptNo").attr("onfocus", "this.blur()"); $("#receiptNo").css("cursor", "not-allowed"); }else{ $("#receiptNo").css("background", ""); $("#receiptNo").removeAttr("onfocus") $("#receiptNo").css("cursor", "text"); } }
html
<li class="clear fl pdd"> <span class="tips2"><span class="red" style="padding-left: 0;">*</span>变更类型:   </span> <p class="fl"> <select id="changeType" name="changeType" onchange="zhihui(this.value)" style="width:167px;"> <option value="">请选择</option> <c:forEach items="${changeTypes }" var="vu"> <option value="${vu.dictValue }">${vu.dictName }</option> </c:forEach> </select> </p> </li> <li class="clear fl pdd"> <span class="tips2"><span class="red" style="padding-left: 0;">*</span>收据编号:   </span> <p class="Long_mr gray input clear"> <span> <input type="text" id="receiptNo" name="receiptNo" class="specialSign"/> </span> </p> </li>
