How to use Javascript to determine the size of an image is actually as simple as writing a function, which of course many people don’t know how to do. Found that using ASP to judge the size of the picture than a number of cattle is complicated, and judged on the judgment, but also logic display. . Pest. With Javascript, it’s easy to do, and the end result is not to let the big picture burst the page.

<script LANGUAGE= " JAVASCRIPT " >

//Check if the image size is larger than expected. Greater than shows the expected size

function show ( chkw )  { //chk images width

if ( chkw>500 )  {

chkw=500;

}

else {

chkw=chkw;

}

return chkw;

}//shawl.qiu script

//example <img src= " images/teach/opera/01.jpg "  onload= " this.width=show ( this.width )"  >

</script>

1. Mouse over the automatically selected check box:

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

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

2.ACCESS  List the number of days of the week that a given day falls on

//This algorithm took me an hour or so

 Querying for all days of the week to which a date belongs

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 to copy the text,   Now, just double click

<script LANGUAGE= " JAVASCRIPT " >

function ClipBoard ( tdObj )  { //IE Only

var holdtext = document.all [' holdtext' ] ;

holdtext.innerText = tdObj.innerText;

Copied = holdtext.createTextRange (a) ;

Copied.execCommand (" Copy "). ;

alert (" text copied "). ;

}

</script>

<form NAME= " form1 "  METHOD= " post "  ACTION= "" >

<ttextarea id= " holdtext "  style= " display:none "  ROWS= " 10 " ></ttextarea>

</form>
