Question

所以我正在使用此链接中的示例代码 Select Cells On A Table By Dragging 建立一个数字1-192的网格，这部分工作得很好，但我很好奇我将如何返回＆＃34;突出显示＆＃34;细胞到PHP？

这可能需要对您的具体情况稍作修改，但它应该非常接近您的需要。我已经包含了一些评论来表明发生了什么。

// bind a click handler to your button
$("input[name='test']").on("click", function() {

    var selectedValues = [];

    // iterate through each of the highlighted cells
    $(".highlighted").each(function(){
        // push the content of the current cell into the array
        selectedValues.push($(this).text()); 
    });

    // invoke ajax to send the data to your server
    $.ajax({
        url: "http://yourdomain.com/somepage.php",
        method: "GET",
        data: {
            selectedValues: selectedValues
        },
        success: function(){
            alert("It Worked!");
        },
        error: function(){
            alert("It Didn't Work :(");
        }
    });
});

将突出显示的单元格返回php
