I have two buttons: btnAdd
and btnUpdate
. I have written a jquery function for button btnUpdate
to validate some fields in the web page like:
我有两个按钮:btnAdd和btnUpdate。我已经为按钮btnUpdate编写了jquery函数来验证web页面中的一些字段,比如:
$(function() {
$('#<%=btnUpdate.ClientID %>').click(function() {
code here
});
});
I want to do the same thing when btnAdd
is clicked. So I have to write the same function again for btnAdd. Is there other way to avoid this?
我想在单击btnAdd时做同样的事情。所以我要为btnAdd写同样的函数。还有其他方法可以避免这种情况吗?
(If I write one javascript function and call the same function in the button click event of both buttons, it's fine. But is there any way using jQuery?)
(如果我编写一个javascript函数,并在两个按钮的按钮单击事件中调用相同的函数,就可以了。但是使用jQuery有什么方法吗?

Just make a selection of two buttons, separated by a comma: ("#add, #update").click...
Looks like this in your code:
只需选择两个按钮,用逗号分隔:(“#add, #update”).单击…在你的代码中是这样的:
$(function() {
$('#<%=btnUpdate.ClientID %>, #<%=btnAdd.ClientID %>').click(function() {
code here
});
});

There are two ways.
有两种方法。
(1) Select both elements at once and apply the event handler to them:
(1)同时选择两个元素,并对其应用事件处理程序:
$(function() {
$('#<%=btnUpdate.ClientID %>, #<%=btnAdd.ClientID %>').click(function() {
code here
});
});
(2) Give the function a name, rather than leaving anonymous:
(2)给函数一个名称,而不是留下匿名:
function clickHandler() {
// code here
}
$('#<%=btnUpdate.ClientID %>, #<%=btnAdd.ClientID %>').click(clickHandler);

in your case, you should do this:
在你的情况下,你应该这样做:
$(function() {
$('#<%=btnUpdate.ClientID %>').click(function() {
validate($this);
});
$('#<%=btnAdd.ClientID %>').click(function() {
validate($this);

function validate(myButton)
{
// code here
}
As you should always do.
就像你应该做的那样。
but as jQuery you can have selectors with multiple inputs, so all you need to do is:
但作为jQuery,您可以使用具有多个输入的选择器,所以您只需:
$('#<%=btnUpdate.ClientID %>, #<%=btnAdd.ClientID %>').click(function() {
validate($this);

jQuery is a JavaScript framework, not another language, so you can write one JavaScript function here too.

function validateFields(e) {

$(function() {
