添加事件处理程序 [英] adding an event handler

问题描述

我在应用程序中动态生成一个表，具体取决于数据库中存在的记录。我遇到的问题是当我尝试为每条记录分配一个事件处理程序时。我在每行的末尾都包含一个图像，点击后应该运行一个函数。继承我的代码，但onClick不起作用。

I am dynamically generating a table in my application depending on what records exist in the database. The problem I am having is when I try to assign an event handler to each record. I am including an image at the end o each row that when clicked should run a function. Heres my code but the onClick doesn''t work.

推荐答案

Just在cellview.appendChild（view）之后尝试这段代码;只需插入一行


[HTML]视图图标

var cellview = row.insertCell（3）;

var view = document.createElement（" img"）;

view.src =" view.gif";

view.onClick = function（）{go（）;}

view.alt =" View";

cellview.appendChild（view）;

cellview.innerHTML = cellview.innerHTML

[/ HTML]


希望它能运作。如有任何疑问，请将其发回论坛

Just try this code, after the cellview.appendChild(view); just insert a line

[HTML] view icon
var cellview = row.insertCell(3);
var view = document.createElement("img");
view.src="view.gif";
view.onClick=function(){go();}
view.alt = "View";
cellview.appendChild(view);
cellview.innerHTML = cellview.innerHTML
[/HTML]

hope it will work. If any prob post back it to the forum

我已设法添加活动处理程序通过将图像附加到div并将事件处理程序添加到div。我现在面临的问题是我为每条记录分配的变量需要不同。继承我的代码

I have managed to add the event handler by appending the image to a div and adding the event handler to the div. The problem I now face is that the variable I assign needs to be different for each record. Heres my code

第一篇文章中的代码问题是onClick。需要onclick。 JavaScript区分大小写。哪个变量需要不同？

The problem with the code in the first post was that "onClick" needed to be "onclick". JavaScript is case-sensitive. Which variable needs to be different?
