js
//重新渲染表单 function renderForm(){ layui.use('form', function(){ var form = layui.form();//高版本建议把括号去掉,有的低版本,需要加() form.render(); }); } //增加产品类别按钮点击事件 function addProductClassify(){ layer.open({ type:1, btn:['确定','取消'], content:$("#select_prod"), area:['270px','160px'], //当前层索引参数(index)、当前层的DOM对象(layero) yes:function(index,layero){ //获取input输入的值 var ivalue=$(layero).find("input").val(); //获取要添加的option的索引 var sIndex=$("#zcySelect")[0].options.length-1; if(ivalue==null||ivalue==''){ layer.msg("请输入产品类别") } else{ layer.msg("输入的产品类别是:"+ivalue); //为select添加option $("#zcySelect").append("<option value="+sIndex+">"+ivalue+"</option>"); renderForm();//表单重新渲染,要不然添加完显示不出来新的option layer.close(index); } $(layero).find("input").val(''); } }) }
