substring ?

[find clausen]

How do i find the value next to width= (500)
in:

'"../graphics/press/012.jpg" width=500 height=339'

 

[e]

var theString = '"../graphics/press/012.jpg" width=500 height=339';
var theWidth = parseInt(theString.substr(theString.indexOf('width=') + 6));
var theHeight = parseInt(theString.substr(theString.indexOf('height=') +
7));

Hi,

Assuming that the number of digits in the width is not a certainty
(ie. could be 500 or 67 or 1005) then you can do it by splitting the
string on a space, looping the results to find the width, and
splitting the width on the equals sign. Just like this...

function getWidth() {
img = "../graphics/press/012.jpg' width=23 height=339";
imgArray1 = img.split(" ");
for (i=0; i<imgArray1.length; i++) {
if (imgArray1.indexOf("width=")!=-1) {
imgArray2 = imgArray1.split("=");
imgWidth = imgArray2[1];
alert(imgWidth);
}
}
}

btw - I flipped the quotes, but I think it can work either way.

best,

jon

Thanx, in the mean time I found out to do it like this:

var str = photo[conv];
var pos=photo[conv].indexOf("=") + 1;
var wdt = str.substr(pos,3)

conv = a the number.

It is used to set the with of a text box below the picture in a
slideshow ...

It is always 3 . 300,400,500,350 ......

str = '"/graphics/press/012.jpg" width=500 height=339';
value = (str.match(/width=(\d+)/))[1];
alert(value);
