我试图创建一个表，其中包含两列和一个条目来修改它们，第一行后的修改符函数开始执行两次，使其无法写入第二列。
这是修改器的功能：

function mdflv(){
    
    $("#mdfTbl").keyup(function(event){
        if (event.keyCode == 13 && getData(this)!=''){
            if ($(this).parent().attr('id').split('.')[1].split('_')[1] == '0'){//This means if the position is 0 the position is in the id the number before the _td
                $("#attrTbl").attr('col', '0');
                father = $(this).parent();//Searching the father.
                $("body").append($(this));
                $(this).hide();
                if (exist(getData("attrTbl"), getData($(this))) == false){
                    //If theres no duplicate...
                    td = document.createElement('TD');//Creating the new TD
                    $(td).attr('id', $("#attrTblBd").children().length+'.td_1');//Adding the ID.
                    $(father).parent().append(td);//Appending the td to the grand father AKA: the body of the table.
                    $(father).append(getData($(this).attr('id')));//Appendding the data.
                    $(td).append(this);//Appending the modifier to the new TD
                    $(this).attr('value', '');//Cleaning
                    $(this).focus();//Focus again.
                    $(this).show();
                }else{
                    father.append(this);
                    $(this).show();
                }
                return false;
            }else{
                var newCont = parseInt($("#tbody1").children().length)+1;
                //getting the td that will store the data.
                var father = $(this).parent();
                //Appending the data to the TD.
                $(father).append(getData(this));
                //This going to be the next td  
                var td = document.createElement('TD');
                $(td).attr('id', (newCont)+'_td.0');
                $(td).append(this);
                var tr = document.createElement('TR');
                $("#attrTblBd").append(tr);
                $(tr).attr('id', (newCont)+'_tr');
                $(tr).append(td);
                $(this).attr('value', '');//Cleaning
                $(this).show();
                $(this).focus();//Focus again.
                return false;
            }
        }
    });
}

这是HTML

你还没有附上你的相关标记。但我猜这个事件是从它的来源bubbling。
您可能需要重新检查处理程序的附加位置，如果需要，可以使用e.stopPropogation()来防止冒泡
还是你的处理程序中的原始return false;。

我遇到了类似的问题-我使用计数器进行了巡视：

$(document).ready(function () {

    var handledCount = 0;

    $("#imageUrl").keyup(function () {
        if (handledCount == 0)
        {
            //method logic
            handled = true;
        }
        handledCount++;
        if (handledCount == 2)
            handledCount = 0;
        return false;
    });
