Funny behavior in jqGrid

Question

so i am working with the navigation bar and I add this code to the delete options

onclickSubmit: function (options, rowid) {
    var rowData = jQuery(this).jqGrid('getRowData', rowid);
    var params ={amount:rowData.amount,account:rowData.account.replace(/-/g,"")};

    return params;
},

and it works just fine. now when i add the same to edit options, it does not work ! when i try an alert(rowData.account) it shows undefined ! while at the same time, the same alert with the same parameter in delete options displays the correct value !

can anyone figure out whats going on here. right now i have to muse the following code in edit options

onclickSubmit: function (/*options, rowid, rowObject*/) {

    //var roData = jQuery(this).jqGrid('getRowData', 8);
    var s;

    s = jQuery("#list").jqGrid('getGridParam','selarrrow');
    var dataF = jQuery('#list').jqGrid ('getCell', s[0], 'account');

    return {account:dataF.replace(/-/g,"")};
},

i get really confused whenever i see these examples showing parameters like options, rowid, rowObject being passed. some examples pass 2 parameters while others pass 3 while others pass none at at all and all of their code works !

and how do we know that say, options is a keyword or not. what about rowid ? some people use rowId and that works too !

Is there any documentation which explains:

1) type and number of parameters for each jqGrid function

2) keywords or reserved words for jqGrid functions

i have a big presentation coming up and they will grill me for sure. i have no idea how the jqGrid works or why it does what it does because the behavior of most jqgrid functions is so erratic. Maybe I feel this way as I am a newbie but please if someone can throw some light on these issues i would be very grateful

thanks

It's a little uncomfortable, but the onclickSubmit of form editing has no rowid parameter. You can get it from postdata:

onclickSubmit: function (options, postdata) {
    var rowid = postdata[this.id + "_id"]; // postdata.list_id
    ...
}

By the way to be exactly the second parameter of onclickSubmit in case of Delete operation is also postdata which is rowid only if musltiselect: true option is not set or if selected only one row. If multiselect: true are used and more as one row selected to delete then postdata will be comma separated string with ids of deleting rows (see the documentation).

so what exactly is postdata ? is it aan array of all the data that would be passed to the server ? and what about options ? options is the most annoying as I can never figure out what it is ! thanks for all your help and patience @oleg – AbtPst Jul 12 '13 at 15:15
@user2334092: The `options` parameter of `onclickSubmit` is object which saves the options of `editGridRow` (the second parameter of `editGridRow`). The initial `options` of `editGridRow` will be a little modified and the current state of the options you can access in `onclickSubmit` for example. You can for example modify `url` here to access RESTful service which required to have `id` as part of URL of Edit operation instead of sending it as part of reques body. `postdata` build mostly the body of the message with will be send to the server. – Oleg Jul 12 '13 at 15:22
@user2334092: See [the answer](http://stackoverflow.com/a/17258545/315935) or [this one](http://stackoverflow.com/a/7365228/315935) for more information about the usage of `options`. – Oleg Jul 12 '13 at 15:24
so, are options and postdata keywords ? what about rowObject and rowid ? i just want to know whether these are predifened keywords in jqgrid or a user can name them anything and the first parameter will always be treated as 'options' ? – AbtPst Jul 12 '13 at 15:27
@user2334092: It's just the names of parameters. `keywords` can exist only in the computer language (like `if` or `else`). I can't answer what it `rowObject` and ehich exactly format it has. You should post exact name of callback which you mean. `rowid` is mostly the value of `id` attribute of the grid row (of `` element of the ``). You can choose *any* name of parameters of your callback functions. It's better to use the name which more corresponds to the *actual* parameters of the callback.

i can understand, thats what makes it so confusing. i'll do some more digging into the documentaion. thanks @oleg ! – AbtPst Jul 12 '13 at 15:41
@user2334092: You are welcome! I would recommend you to use `jquery.jqGrid.src.js` instead of `jquery.jqGrid.min.js` and **debug jqGrid code**. In the way you can better understand the implementation of jqGrid. [The source](https://github.com/tonytomov/jqGrid) of jqGrid on github is another good place. One more good source are code fragments from old stackoverflow answers. I post frequently the demo which you can debug and better understand how all works on the example. – Oleg Jul 12 '13 at 15:45
