为layer.prompt增加输入框提示
打开 layer.js,用搜索工具找到prompt一行代码,下图为修改以后的:
注:原代码的单引号和双引号的使用
这是用格式化工具格式化了
r.prompt = function(e, t) { var a = ""; if (e = e || {}, "function" == typeof e && (t = e), e.area) { var o = e.area; a = 'style="width: ' + o[0] + "; height: " + o[1] + ';"', delete e.area } var s, l = 2 == e.formType ? '<textarea class="layui-layer-input"' + a + ' placeholder="' + (e.placeholder?e.placeholder:'') + '"></textarea>': function() { return '<input type="' + (1 == e.formType ? 'password': 'text') + '" placeholder="' + (e.placeholder?e.placeholder:'') + '" class="layui-layer-input">' } (), f = e.success; return delete e.success, r.open(i.extend({ type: 1, btn: ["确定", "取消"], content: l, skin: "layui-layer-prompt" + c("prompt"), maxWidth: n.width(), success: function(t) { s = t.find(".layui-layer-input"), s.val(e.value || "").focus(), "function" == typeof f && f(t) }, resize: !1, yes: function(i) { var n = s.val(); "" === n ? s.focus() : n.length > (e.maxlength || 500) ? r.tips("最多输入" + (e.maxlength || 500) + "个字数", s, { tips: 1 }) : t && t(n, i, s) } }, e)) },
引用方法:
layer.prompt({ formType: 0, //输入框类型,支持0(文本)默认1(密码)2(多行文本) maxlength: 12, //限制长度 value: '', //初始时的值,默认空字符 title: '标题', //标题 placeholder: '提示信息', //提示信息,默认空字符 area: ['400px', '22px']//自定义文本域宽高 }, function(value, index){ console.log(value,index); layer.close(index); });
效果:
