因为ayer.confirm的按钮并非采用button,而是a标签,所以获取按钮焦点获取不到,要采用别的方法,下面介绍在ie11中和ie8中不同的写法
在ie11中
javascript
layer.confirm('确定取消这个弹窗吗?',{
btn: ['确定', '取消'],
success:function(layero){
//获取焦点
var btn = layero[0].getElementsByClassName('layui-layer-btn')
[0].getElementsByTagName('A')[0];
btn.href = 'javascript:void(0)';
btn.focus();
},
title:"提示"
},function(index){
layer.close(index);
//你的操作
});
})
在ie8中不支持getElementsByClassName方法,我们需要对它做额外的处理
javascript
layer.confirm('确定取消这个弹窗吗?',{
btn: ['确定', '取消'],
success:function(layero){
//获取焦点
var btn = getElementsByClassName('layui-layer-btn')
[0].getElementsByTagName('A')[0];
btn.href = 'javascript:void(0)';
btn.focus();
},
title:"提示"
},function(index){
layer.close(index);
//你的操作
});
})
重写getElementsByClassName方法
javascript
var getElementsByClassName = function (searchClass, node,tag) {
var result = [];
node = node || document;
tag = tag || "*";
var classes = searchClass.split(" "),
elements = (tag === "*" && node.all) ? node.all: node.getElementsByTagName(tag),
patterns = [],
current,
match;
var i = classes.length;
while (--i >= 0) {
patterns.push(new RegExp("(^|\\s)" + classes[i] + "(\\s|$)"));
}
var j = elements.length;
while (--j >= 0) {
current = elements[j];
match = false;
for (var k = 0,
kl = patterns.length; k < kl; k++) {
match = patterns[k].test(current.className);
if (!match) break;
}
if (match) result.push(current);
}
return result;
}
后种方法是兼容的不怕麻烦的可直接采取后种方法
