type of link is .doc doc.links.everyItem().update(); not work

Some pertinent questione would be

• How did you conclude that it's not working. Do you get any errors?
• Does this happen with only this doc link or all the links in this file.
• How about executing this code on another INDD file, what happens in that case?

Totally working on my side. Which InDesign version are you running? 

Hi @laurence roussel12011930 ,

your code should work for all placed and linked images.

You could also test something else:

// Create an array of all links of the document:
var allLinks = app.documents[0].links.everyItem().getElements();

// Loop the array:
for( var n=0; n<allLinks.length; n++ )
{
allLinks[n].update();
};

Or use relink(File) in the loop.

So you do a relink to the same file:

// Create an array of all links of the document:
var allLinks = app.documents[0].links.everyItem().getElements();

// Loop the array:
for( var n=0; n<allLinks.length; n++ )
{
allLinks[n].relink( allLinks[n].filePath );
};
