what is difference between _set() and direct assign to a variable

Hi Sahi Team/ User,


what is the difference between using _set() and direct assigning a value to variable


Below is the over all code

var $pagNoStartFrom = 10
var $links = _collect("_link", "/./", _in(_div("idName")));
var $paginationLen = $links.length;
$paginationLen--;


_set($lastPaginationNo, $links[$paginationLen].text);


if( parseInt($pagNoStartFrom) < parseInt($tempLastPaginationNo) ) {
    $paginationLen--;
    _set($lastPaginationNo, $links[$paginationLen].text);
}

var $pagNoStartFrom = 10
var $links = _collect("_link", "/./", _in(_div("idName")));
var $paginationLen = $links.length;
$paginationLen--;


var $lastPaginationNo = $links[$paginationLen].text;


if( parseInt($pagNoStartFrom) < parseInt($tempLastPaginationNo) ) {
    $paginationLen--;
    _set($lastPaginationNo, $links[$paginationLen].text);
}

Example:

_set($lastPaginationNo, $links[$paginationLen].text); // this is working fine

var $lastPaginationNo = $links[$paginationLen].text; // but this is not working

from the above code, 1st code is working fine where i have used _set() method

when i use directly assinging a value to variable is not working fine


sahi scripts is same as javascript, when this is working fine in javascript then y it is failing in sahi

pls let me know the reason why its not working


thanks in advace

Hi

as you might know, Sahi differentiates between browser and proxy context. var $x = 1 would be declaring a proxy variable. $x = _image(1) is just creating a element stub in the proxy. When accessing the image like _image(1).name the browser context is checked for the image. _set is used to bring something from the browser context into the proxy. $x=_image(1).name is stored as is, internaly $x would be "_image(1).name". Whereas _set($x, _image(1).name) really reads the values from the browser context. $x would be "imageName".
As it is kinda confusing when to use _set, rule of thumb is to always use it (or _getText/_getValue or _condition) when you access something on the browser.

Does the make the meaning of set more clear?

Does a _condition() in your if case of the second example work?
