I am doing some tests with differents browsers using the Selenium::Remote::Driver
module.
I would like to check if I find some item in my web site list, list from a framework JavaScript (which creates grids). For this case I have to use JavaScript snippet allowed by Selenium::Remote::Driver
.
I wrote the following code
$script = q{
var paramProgramName = arguments[0];
var list = $('#c-list').dxList('instance');
var items = list.option('items');
var index = items.findIndex(function(el){ return el.name == paramProgramName; });
list.selectItem(index);
return ;
};
$driver->execute_script($script, $programName);
It works fine with Chrome and Firefox but not with Internet Explorer because the findIndex
method is only supported by version 12 and following. For some reason I have to use version 11.
What can I do differently to get an index from every browser?
So my question is how can i do differently to get my index for every browser ?
You have at least three options:
Shim Array#findIndex
; MDN has a shim/polyfill you can use.
Use something else that IE11 has, such as Array#some
(which even IE9 has):
var index = -1; items.some(function(el, i) { if (el.name == paramProgramName) { index = i; return true; } });
Use something else that even IE8 has, such as for
:
var index = -1; for (var i = 0; i < items.length; ++i) { if (items[i].name == paramProgramName) { index = i; break; } }
you can use http://underscorejs.org/ ,
how to use:
var index = _.findIndex(objects, function(item){
return item.name == programName;
});
A better way:
var findArrayIndex = function (array, predicateFunction) {
var length = array == null ? 0 : array.length;
if (!length) {
return -1;
}
var index = -1;
for (var i = 0; i < array.length; ++i) {
if(predicateFunction(array[i])) {
index = i;
break;
}
}
return index;
}
Usage:
findArrayIndex(cachedAnnouncementsArray, function(o){return o.ID == 17;});
Another way:
var objects = [
{ 'key' : 1, 'name' : 'ABC' },
{ 'key' : 2, 'name' : 'QLP' },
{ 'key' : 3, 'name' : 'XYZ' },
];
function filterByKey(obj) {
if ('key' in obj) {
return obj.key === 'some_value';
}
}
var index = objects.indexOf(
objects.filter(filterByKey)[0]
);
Instead of:
const index = items.findIndex(el => el.name == paramProgramName);
You can achieve the same result in two IE9 operations like so:
const index = items.indexOf(
items.filter(el => el.name == paramProgramName)[0]
);
