1. console报错 可以用alert代替
2. borde-radius不兼容
3.backage 添加背景图片 即使设置固定宽高不会压缩只会裁切 因为无法设别backage-size 调整北京图片大小适应ie8 大屏通过js 更改背景图
4./* 去除ie input 后X */
input::-ms-clear, input::-ms-reveal{
display: none;
}
5. ie8和ie9 不兼容 new FormData() 文件上传需要 不支持ie8和ie9 解决办法暂时未
var funPlaceholder = function (element) { var placeholder = ‘‘; if (element && !("placeholder" in document.createElement("input")) && (placeholder = element.getAttribute("placeholder"))) { element.onfocus = function () { if (this.value === placeholder) { this.value = ""; } this.style.color = ‘white‘; }; element.onblur = function () { if (this.value === "") { this.value = placeholder; this.style.color = ‘white‘; } }; //样式初始化 if (element.value === "") { element.value = placeholder; element.style.color = ‘white‘; } } }; $(document).ready(function () { funPlaceholder(document.getElementById("startNum")); })
