If the hardware API happens to have a JavaScript interface then great!
If it does not, which would be the normal state of affairs, you'll need to build a middleware webservice that interfaces with the driver. Likely candidates for the middleware language are C-family or Java.

I have a ng-grid that I am trying create a wrap-text column for a column that contains multiple lines of comment text. I have been trying everything today that I can find on the internet and still can't find a solution. I want to show you my code and if someone can tell me a better way of doing this that would be a great help.
.gridStyle4 {
border: 1px solid #dfdfdf;
overflow-y: scroll;
}
<div style="margin-top:100px;">
<hr style="height:1px; background-color: silver; border:0px; margin-top:0px; margin-bottom:10px;" />
<div class="gridStyle4" ng-grid="gridOptions" />
<div class="pagination">
<ul>
<li ng-class="{disabled: currentPage == 1}">
<a ng-click="prevPage()">« Prev</a>
</li>
<li ng-repeat="n in range(GridPagingOptions.totalPages)" ng-class="{active: n == currentPage-1}" ng-click="setPage()"><a ng-bind="n + 1">1</a>
</li>
<li ng-class="{disabled: currentPage == GridPagingOptions.totalPages}">
<a ng-click="nextPage()">Next »</a>
</li>
</ul>
</div>
</div>
$scope.gridOptions = {
data: 'myData',
enablePaging: true,
pagingOptions: $scope.GridPagingOptions,
sortInfo: {
fields: [],
columns: [],
directions: []
},
useExternalSorting: false,
showFooter: false,
columnDefs: [{
field: 'RequestNumber',
width: 90,
displayName: 'RequestID'
}, {
field: 'ActionByName',
width: 160,
displayName: 'Action }, { field: '
ActionDate ', width: 90, displayName: Action Date',
cellFitlter: "date:'yyyy-MM-dd'"
}, {
field: 'Comments',
width: 125,
displayName: 'Comments'
}, {
field: 'ApproverComments',
displayName: 'Approver Comments',
rowHeight: 25,
width: 215,
cellClass: 'wrap-text',
cellTemplate: '<label id="approverC" name="approverC" title="{{ row.getProperty(col.field)}}">{{ row.getProperty(col.field)}}</label>'
}]
};

I think I found an answer. I found out that someone used a textarea to do this but I still can't get it to work. Here is what I'm doing:
{ field: 'ApproverComments', enableCellEdit: false, width: 215, cellClass: 'wrap-text', cellTemplate: '' }
|
|
|
|

Sorry,
In my last post I miss spelled model. Here is the correct code and it still only shows an empty editable textarea and not the model text.
{ field: 'ApproverComments', enableCellEdit: false, width: 215, cellClass: 'wrap-text', cellTemplate: '<textarea ng-model="ApproverComments"></textarea>' }

We are using Viewer which load .jpeg file. Viewer is built by JavaScript Code. we are also using Rotation annotation but it is not working. below mention is the snippet of code.
Viewer.RotatePage = function() {
if(Viewer.CanRotate)
{
RealDocNo = Viewer.CurrentDocument - 1;
RealPageNo = Viewer.CurrentPage -1;
Viewer.Documents[RealDocNo].PageOrientation[RealPageNo] = Number(Viewer.Documents[RealDocNo].PageOrientation[RealPageNo]) +1;
if(Viewer.Documents[RealDocNo].PageOrientation[RealPageNo] == 4)
Viewer.Documents[RealDocNo].PageOrientation[RealPageNo] = 0;
document.getElementById("ThumbnailImage_"+Viewer.CurrentDocument+"_"+Viewer.CurrentPage).style.filter = "progid:DXImageTransform.Microsoft.BasicImage(rotation="+Viewer.Documents[RealDocNo].PageOrientation[RealPageNo]+")";
document.getElementById("PageImage_"+Viewer.CurrentDocument+"_"+Viewer.CurrentPage).style.filter = "progid:DXImageTransform.Microsoft.BasicImage(rotation="+Viewer.Documents[RealDocNo].PageOrientation[RealPageNo]+")";
if (js_HideAnnotations!="true") {
Viewer.LayoutAnnotations(Viewer.CurrentDocument);
Viewer.LayoutHilites(Viewer.CurrentDocument);
}
}
}
even we are not getting any error. please help us to resolve this issue.

Yes, we can do it from JavaScript.
set unique id property of all element.
<area shape="rect" id="Shape1" coords="0,0,82,126" href="sun.htm" alt="Sun">
Access that id in Javascript code apply set src as you want.

So I have this row that's a cart item. And inside the row are column divs with spans for values.
I manage to isolate the div row, and I'm trying to find the the spans and change the values.
I tried each, but it seems to grab all the elements, and not step through each one.
I'm stumped on this.
So my HTML looks like this, and I want to change the value of span data-qty attr and the inner html inside the span tag.
<div class="cartRecord" onclick="service_selectItem(17);" data-serviceid="1" data-cartid="17">
<div class="cartQty">
<span data-qty="7">7</span>
</div>
<div class="cartSKU" id="1000">
<span>1000</span> </div>
<div class="cartDescription">
<span>Diagnose and repair hardware or software</span>
</div>
<div class="cartPrice">
<span>95.00</span>
</div>
<div class="cartTotal">
<span data-total="665">665.00</span>
</div>
</div>
This is what I have going, if my thoughts are way off track I'm open to suggestions.
success: function (data) {
if (data !== null) {
var dRecord = $('div.cartRecord[data-cartID="' + _cartID + '"]');
if (dRecord !== null) {
dRecord.each(function(index, element) {
alert($(this).html());
if ($(this).is('span')) {
alert($(this).html());
if ($(this).attr('data-qty')) {
alert($(this).html());
$(this).data('data-qty', data.Qty).html(data.Qty);
}
}
if ($(this).is('span')) {
alert($(this).html());
if ($(this).attr('data-total')) {
alert($(this).html());
$(this).data('data-total', data.Total).html(data.Total);
}
}
});
}
}

The each function iterates through all of the elements matched by the selector - ie: the div elements with the specified data attribute. It doesn't iterate over the descendants of the matched items, which is what you're trying to do.
You don't actually need to iterate over the descendants. You can just find the relevant span elements and update them directly:
var dRecord = $('div.cartRecord[data-cartID="' + _cartID + '"]');
dRecord.find("span[data-qty]").html(data.Qty).data("qty", data.Qty);
dRecord.find("span[data-total]").html(data.Total).data("total", data.Total);
Also worth noting that the return from the $ function will never be null. If there are no matching elements, you'll still get a jQuery object back, with a length of zero.

I feel stupid now. That's sort of how I found the the data I needed in another function.
very simple and elegant.
I didn't think of or forget about find.
I added the dRecord Check as length instead of null or undefined. Maybe I don't need it.
The data-qty and data-total didn't change, but I can figure that out.
success: function(data) {
if (data !== null) {
var dRecord = $('div.cartRecord[data-cartID="' + _cartID + '"]');
if (dRecord.length > 0) {
dRecord.find("span[data-qty]").html(data.Qty).data("data-qty", data.Qty);
dRecord.find("span[data-total]").html(data.Total.formatMoney(2, '.', ',')).data("data-total", data.Total);
}
} else {
$("#serviceUpdate").removeClass('btn btn-default').addClass('btn btn-danger');
}
}
Oh this MVC and the Twitter Bootstrap CSS is hard to implement, but getting better at it. And faster.
Thanks Richard, I was completely off the rails on this.

Just to throw on the pile a little more, have you considered using a data-binding framework like Knockout, Backbone, or Angular? They do have the benefit of working on data as if it's at the base data level, rather than having to reverse-engineer the data from a rendered view.
|
|
|
|

No I haven't considered it. I heard of Angular but have no clue what it is.
Nathan Minier wrote: rather than having to reverse-engineer the data from a rendered view.
But I rendered the content in the view with JQuery after the GET call.
I mean I used jQuery to download the cart items and construct the HTML for it.
Then wrote this post to update the item qty and total price.
Feel free to elaborate ...

Well, general JavaScript and jQuery do not support any sort of data binding, so when data is modified for any reason you may miss it, or use JavaScript to walk the DOM until you locate the appropriate element.
Data binding frameworks eliminate this necessity. You can use them to bind a JavaScript variable to an element on the DOM. This means that when a value is updated either from an AJAX call or from user interaction, the change reflects in both the script and on the DOM.
For instance, I could rewrite your sample as:
<html ng-app="myApp">
...
<div ng-controller="myCartController">
<div class="cartRecord" ng-click="doSomething()">
<div class="cartQty">
<input type="text" ng-model="model.quantity" />
</div>
<div class="cartSKU">
<span>{{model.SKU}}</span> </div>
<div class="cartDescription">
<span>{{model.Description}}</span>
</div>
<div class="cartPrice">
<span>{{model.price | currency : '$' : 2}}</span>
</div>
<div class="cartTotal">
<span>{{model.total}}</span>
</div>
</div>
</div>
<script type="text/javascript">
angular.module('myApp',[])
.controller('myCartController',['$scope',function($scope){
$scope.model = MethodToGetModelFromAJAX();
$scope.model.total = $scope.model.price * $scope.model.quantity;
$scope.doSomething = function(){
}
}
</script>
</html>
Never mind the Angular-specific syntax, that code will allow you to populate the HTML via AJAX, update the quantity and recalculate the total, format the currency, and will even "do something!" on click.

That sounds and looks cool!
That may reduce my development time, after the learning curve.
So this is what most folks are using today? and is well accepted?
I'm pretty far behind on MVC, and need to catch up.

It seems to go one of two ways (in the ASP.NET world).
The first is .NET MVC where the majority of the work is done server-side, so data-binding in JavaScript isn't terribly important. The problem is that it relies on postbacks and viewstate. In those formats state is tracked on the server so JavaScript needs are generally fairly minimal.
The other common pattern is the Single-Page Application using WebAPI and a data-binding framework (mine's Angular, hence the example). You use flat HTML as templates and only serve data from your controllers. This approach getting more common, because it can do a very solid job of acting like a native application. State resides on the client in this format, and the ASP.NET modules just provide data.
Hybrid approaches like the one you describe, where you use MVC with AJAX, do happen, but by and large people lean one way or the other due to the complexity of managing state on both server and client side.

I think you're getting confused between WebForms and MVC.

Meh, ViewData.
Session cookie is still sort of the same thing though. Ish.
I won't debate it, though, or you'll start quoting GUIDs at me from memory.
