1.js中apply和Math.max()函数的问题
function getMax(arr){
return Math.max.apply(null, arr);
}
var arr=[1,3,6,3,7,9,2];
console.log(Math.max.apply(null,arr));
获取表格中td最大值
function getMax(arr){ ?return Math.max.apply(null, arr);}function getTdMax(td){ ???var arr=[]; ???for(var i=0;i<td.length;i++){ ????var ct=parseInt(td[i].innerHTML); ????arr.push(ct); ????} ????console.log(arr); ????var max=getMax(arr); ?????console.log(max); ?????for(var i=0;i<td.length;i++){ ??????????????if(td[i].innerHTML==max){ ??????????????????td[i].innerHTML=‘<i class="iconfont icon-huangguan"></i>‘+max; ??????????????????td[i].setAttribute(‘title‘,‘最大值‘); ??????????????} ??????????}}function trMax(){ ?getTdMax($("#contrastTable tr:eq(2) td:not(td:nth-child(1),td:nth-child(2))")); ?getTdMax($("#contrastTable tr:eq(3) td:not(td:nth-child(1),td:nth-child(2))")); ?getTdMax($("#contrastTable tr:eq(4) td:not(td:nth-child(1),td:nth-child(2))")); ?getTdMax($("#contrastTable tr:eq(6) td:not(td:nth-child(1),td:nth-child(2))")); ?getTdMax($("#contrastTable tr:eq(7) td:not(td:nth-child(1),td:nth-child(2))"));}trMax();js不懂部分
