Question

我开始使用asp.net编程，我有一个带有一些复选框的表。

问题是，我无法创建静态表，因为此操作与某些参数相关联。无论如何..当我点击First复选框时，我想要反转此表中的其他复选框。我怎么能抓住这个事件？

artboardWidth = 640
Framer.Device.contentScale = (Screen.width / artboardWidth)

var substringMatcher = function (strs) {
                return function findMatches(q, cb) { // an array that will be populated with substring matches
                    var matches = [];

                    // regex used to determine if a string contains the substring `q`
                    //var substrRegex = new RegExp(q, 'i');

                    // we use starts with instead of substring
                    var substrRegex = new RegExp('^' + q, 'i');


                    // iterate through the pool of strings and for any string that
                    // contains the substring `q`, add it to the `matches` array
                    $.each(strs, function (i, str) {
                        if (substrRegex.test(str)) {
                            matches.push(str);
                        }
                    });

                    cb(matches);
                };
            };

你可以试试这段代码

 List<CheckBox> lstChckBox;

    protected void Page_Load(object sender, EventArgs e)
    {
        // you can create controls programaticaly or html page, doesnt important
        //only you should know controls ID and all controls share same checked event
        CheckBox chc1 = new CheckBox();
        chc1.CheckedChanged += new EventHandler(chck_CheckedChanged);
        CheckBox chc2 = new CheckBox();
        chc2.CheckedChanged += new EventHandler(chck_CheckedChanged);
        CheckBox chc3 = new CheckBox();
        chc3.CheckedChanged += new EventHandler(chck_CheckedChanged);


        // Now, you can create a List so event is fired, you can catch which controls checked or not 
        lstChckBox = new List<CheckBox>();
        lstChckBox.Add(chc1);
        lstChckBox.Add(chc2);
        lstChckBox.Add(chc3);
    }

    void chck_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox checkBox = (sender as CheckBox);
        foreach (CheckBox item in lstChckBox)
        {
            if (item != checkBox)
            {
                item.CheckedChanged -= new EventHandler(chck_CheckedChanged);
                item.Checked = !checkBox.Checked;
                item.CheckedChanged += new EventHandler(chck_CheckedChanged);
            }
        }
    }
