Javascript function to check whether the image size exceeds the expected size

I found that using ASP to determine the image size is more complicated than that of taobaomao. When I judge the image size, I will judge it. I also need to display it logically... annoying. it is easy to use Javascript to judge and solve the problem. The final effect is nothing more than making large images break the page.

 

<Script LANGUAGE = "JAVASCRIPT">
// Check whether the image size is greater than the expected size. If the image size is greater than the expected size, it is displayed as the expected size.
Function show (chkw) {// chk images width
If (chkw & gt; 500 ){
Chkw = 500;
}
Else {
Chkw = chkw;
}
Return chkw;
} // Shawl. qiu script
// Example
</Script>

 

1. Check box automatically selected with the mouse cursor:

<Input TYPE = "checkbox" onMouseMove = "checked = true">
<Input TYPE = "checkbox" onMouseMove = "checked = true">

 

2. ACCESS Lists the days of a day in a week.

// This algorithm takes an hour.

Query the data of all days of a day in a week.

SELECT *
FROM ctdate_by_query_date
WHERE dateandtime between (#2006-5-15 # + Weekday (2006-5-15)-6) and #2006-5-15 # + Weekday (2006-5-15)

 

3. Double-click the mouse to copy the text. Double-click the mouse to copy the text.

<Script LANGUAGE = "JAVASCRIPT">
Function ClipBoard (tdObj) {// IE Only
Var holdtext = document. all ['holdtext'];
Holdtext. innerText = tdObj. innerText;
Copied = holdtext. createTextRange ();
Copied.exe cCommand ("Copy ");
Alert ("text copied ");
}
</Script>
<Form NAME = "form1" METHOD = "post" ACTION = "">
<Ttextarea id = "holdtext" style = "display: none" ROWS = "10"> </ttextarea>
</Form>
