给input标签加整数验证

为input 标签添加：

onblur="checkCoordinate(this.id)"

function checkCoordinate(check){

var comCoordinate = document.getElementById(check).value;

//var coordinate="^[0-9]*[1-9][0-9]*$";

if(!(/(^[1-9]\d*$)/).test(comCoordinate)){

alert(0);

$.messager.alert('操作提示', "请输入整数","info" );

}

}
