I recently wrote another project and used innerHTML. However, it is expected that onclick becomes invalid after innerHTML is called, because innerHTML is a button inserted in text format, therefore, The onclick event cannot be identified. We have to find another way out. We cannot implement it directly, but indirectly. The following is an example:
Example 1: onclick is not implemented in this example.
Copy codeThe Code is as follows:
<Html>
<Head>
<Script defer>
Function insCell (th)
Var name = th. name;
Var id = th. id;
If (name = "no "){
Id. innerHTML = "<input type = 'button 'onclick = 'encall( this) 'value = 'hangzhou'
Name = 'no' id = '1'> ";
} Else {
Id. innerHTML = "<input type = 'button 'onclick = 'encall( this) 'value = 'deprecation'
Name = 'yes' id = '1'> ";
}
</Script>
</Head>
<Body>
<Br/>
<Span id = "msg">
<Input type = "button" onclick = "insCall (this)" value = "deprecate" name = "yes" id = "1">
</Span>
</Body>
</Html>
In the preceding example, the button name is used to determine whether to go online or offline ~~~ We found that when you click the button for the first time, it will be invalid if you click it again ~~~~~~
At this time, we can implement it in disguise as follows:
Copy codeThe Code is as follows:
<Html>
<Head>
<Script defer>
Function insCell (th)
{
Var name = th. name;
Var id = th. id;
Alert (name + "--" + id );
Var span = document. getElementById (id );
If (name = "no "){
Span. innerHTML = "<input type = 'button 'value = 'deprecation '> ";
Span. name = "yes ";
} Else {
Span. innerHTML = "<input type = 'button 'value = 'hangzhou'> ";
Span. name = "no ";
}
}
</Script>
</Head>
<Body>
<Br/>
<Span id = "1" onclick = "insCell (this)" name = "no">
<Input type = "button" value = "online">
</Span>
</Body>
</Html>
