我想创建一个循环(结果将被插入到javascript)
语法:
- 第一个数字为日期(星期一-星期五/1 - 5)
- 第二个数字为小时(1 - 11)
所以这就是循环最终应该返回的内容:
subject_1_1: $("#subject_1_1").val(),
subject_2_1: $("#subject_2_1").val(),
subject_3_1: $("#subject_3_1").val(),
subject_4_1: $("#subject_4_1").val(),
subject_5_1: $("#subject_5_1").val(),
subject_1_2: $("#subject_1_2").val(),
subject_2_2: $("#subject_2_2").val(),
subject_3_2: $("#subject_3_2").val(),
subject_4_2: $("#subject_4_2").val(),
subject_5_2: $("#subject_5_2").val(),
subject_1_3: $("#subject_1_3").val(),
subject_5_11: $("#subject_5_11").val()
最后一个元素不能有逗号
// first sets x = 1, then, while x isn't equal to 5 the code
// inside `{ ... }` is executed and x is added 1
for($x=1;$x<=5;$x++){
// again, but this time with y, from 1 to 11.
for($y=1;$y<=11;$y++){
// So we end up here and we now this code is going to execute
// elevent times for each x value, and a total of 5 x values.
// thats (x = from 1 to 5) * (y = from 1 to 11).
// This string is printed (`echo`) every time for each iteration.
echo "subject_1_3: $('"#subject_".$x."_".$y."'").val()".(!($x==5&&$y==11)?",":"")."'n";
}
}
编辑1:现在删除最后一个逗号。
编辑2:添加注释，但阅读:
在打印的字符串中，我注意到以下代码:!($x==5&&$y==11)?",":""
执行以下操作:
if this is true ? this is executed : and if it is not, then this is executed
那么，在pseudo:
中(if not (x=5 and y = 11)) then (print comma) else (don't)
为什么不在JavaScript中做呢?
var obj, x, y;
obj = {}; // this will be the object your subject_X_Y properties belong to
for( x=1; x<=5; x++) {
for( y=1; y<=11; y++) {
obj['subject_'+x+'_'+y] = $('#subject_'+x+'_'+y).val();
}
}
