I have the following in my partial view...
#Model.ServerDetails
<div>
..... various markup
</div>
<script type="text/javascript">
var bs = '#Model.BackupServer';
if (bs == null) {
bs = "";
}
var bssn = bs + '|' + '#Model.ServerName';
$(document).ready( function() {
if (bs != "") {
$getJSON('#UrlContent("~/Details/OtherBackedUpServers?bsn=" + bssn)', function(returnedServers) {
..... removed for brevity...
}
}
});
Unfortunately bssn in the $getJSON() paramater is showing an error: 'bssn' is not declared. It may be inaccessible due to its protection level.
Can someone explain why and how I can correct it?
Thanks
You can't pass JavaScript(Client Side) variable to Url.Action as it is processed at the Server-Side.
As a workaround, you can use placeholder to generate the url. Then use .replace() method to generate the actual url.
var url = '#Url.Action("OtherBackedUpServers", "Details", new { bsn= -1})';
url = url .replace('-1', bssn);
$.getJSON(url );
Or, Better pass the variable as payload
$.getJSON('#Url.Action("OtherBackedUpServers", "Details")', { bsn : -1});
Or write:
$getJSON('#UrlContent("OtherBackedUpServers", "Details")?bsn=' + bssn, function(returnedServers) {
..... removed for brevity...
}
CORRECTION
$getJSON('#Url.Action("OtherBackedUpServers", "Details")?bsn=' + bssn, function(returnedServers) {
..... removed for brevity...
}
Right now I am using a window to view details that are not shown in the grid. I have made my own custom editor in the window as well which hides the details and replaces them with inputs.
Unfortunately I cannot get the Update button to have the same functionality as an update button in the kendo toolbar.
I am using transport and parameter map for my create which works perfectly. I just need to be able to hit the update, which I haven't been able to.
Here is a snippet of code for the template:
<li><b>Change Control Objective</b></li>
<li><textarea type="text" class="k-textbox k-input" data-bind="value:ChangeControlObjective">#= ChangeControlObjective #</textarea></li>
<li><b>Change Control Specifics</b></li>
<li><textarea type="text" class="k-textbox k-input" data-bind="value:ChangeControlSpecifics">#= ChangeControlSpecifics #</textarea></li>
<span class="k-update k-icon k-i-tick"></span>Save
I can't show my JS code but it is based off this dojo: http://dojo.telerik.com/abUHI
UPDATE:
I am able to hit the update in the parametermap off of my save button click but it's sending the old data to the update instead of the new. Here is the button click code:
$("#saveChanges").click(function () {
dataItem.dirty = true;
$("#ccrGrid").data('kendoGrid').saveChanges();
});
Each input has a data-bind attribute and the parametermap looks like this:
case "update":
var changeControlRequestId = options.ChangeControlRequestID;
var changeControlObjective = options.ChangeControlObjective;
var changeControlSpecifics = options.ChangeControlSpecifics;
var productAssociation;
if (options.AccountChangeInfo.ProductAssocation == undefined) {
productAssociation = "";
} else { productAssociation = options.ProductAssocation; }
var amortization;
if (options.AccountChangeInfo.Amortization == undefined) {
amortization = "";
} else { amortization = options.Amortization; }
var productType;
if (options.ProductChangeInfo.ProductType == undefined) {
productType = "";
} else { productType = options.ProductType; }
var productName;
if (options.ProductChangeInfo.ProductName == undefined) {
productName = "";
} else { productName = options.ProductName; }
var productDescription;
if (options.ProductChangeInfo.ProductDescription == undefined) {
productDescription = "";
} else { productDescription = options.ProductDescription; }
var productContract;
if (options.ProductChangeInfo.ProductContractualFeatures == undefined) {
productContract = "";
} else { productContract = options.ProductContractualFeatures; }
var productBehavior;
if (options.ProductChangeInfo.ProductBehavioralAssumptions == undefined) {
productBehavior = "";
} else { productBehavior = options.ProductBehavioralAssumptions; }
var evaluationBehavior;
if (options.ProductChangeInfo.ProductEvaluationBehavior == undefined) {
evaluationBehavior = "";
} else { evaluationBehavior = options.ProductEvaluationBehavior; }
var productStratification;
if (options.ProductChangeInfo.ProductStratificationRoutines == undefined) {
productStratification = "";
} else { productStratification = options.ProductStratificationRoutines; }
if (content.isreadonly == "True") {
alert("you have readonly access");
}
else {
var urlString = "env=" + content.env + "&allyid=" + content.userId + "&changeRequestID" + changeRequestID + "&changeControlObjective=" + changeControlObjective + "&changeControlSpecifics=" + changeControlSpecifics +
"&productAssociation" + productAssociation + "&amortization" + amortization +
"&productType" + productType + "&productName" + productName + "&productDescription" + productDescription +

I've been going through this a couple months ago. Per my extensive research there are 2 key sources for doing custom popup editing in Kendo in entire Internet ;) :
Custom editor template
I aslo created a simplified version of this for you here: http://jsbin.com/qudotag/
to cut the elements which can be expanded once you grap the key concepts. Note that this does not work fully as changes are not persisted. It is expected behaviour, as you would need to define the CRUD operations for the grid (what happens when save, cancel etc. is done).
How to deal with CRUD is available in the second source:
Crud with external form
Some heavy studying of these 2 along with going into some more depths of MVVM (which might be intimidating at first, but then really useful for much smoother work with Kendo) will get you going.
Edit: actually you could do with just first approach, which is easier and retain the state by refreshing the grid after cancel.
In a c# MVC project, I was given a view by a front-end designer that contains this little script:
<script>
$('#PhaseDD').change(function () {
var chosenValue = $(this).val();
$('.ProcessDD').hide();
if (chosenValue == "")
$('#DefaultProcess').show();
if (chosenValue == "Planning")
$('#PlanningProcess').show();
if (chosenValue == "Procurement")
$('#ProcurementProcess').show();
if (chosenValue == "Installation")
$('#InstallationProcess').show();
if (chosenValue == "Closure")
$('#ClosureProcess').show();
});
</script>
I would like to replace all the hard-coded options with a list that comes from the model. Something like this...
<script>
$('#PhaseDD').change(function () {
var chosenValue = $(this).val();
$('.ProcessDD').hide();
if (chosenValue == "")
$('#DefaultProcess').show();
// loop over a list from the model here
if (chosenValue == " loop-item-name ")
$('# loop-item-name + Process').show();
// end loop
});
</script>
Is this possible? If so, how? And am I even going about this the right way? I was thinking I could use razor syntax, but that isn't working.
You can not compare a C# variable to a JS variable. But you can use razor to create a JS variable from a C# variable.
Here is how to fill a JS array with the values of a C# array:
#{
// fetch this from ViewModel if it needs to be dynamic
var cSharpNames = new [] { "Planning", "Procurement"};
}
<script>
var jsNames = []; // this is a JS array
#foreach(var name in cSharpNames) {
<text>jsNames.push(#name);</text>
}
</script>
Then use the indexOf() method to search in the jsNames array as has been shown by Jeremy.
I'd just make an array, check to see if the value exists within it, and if it does show it. Something like this:
<script>
$('#PhaseDD').change(function () {
var chosenValue = $(this).val();
var processes = ['Planning', 'Procurement'];
$('.ProcessDD').hide();
if (chosenValue == "")
$('#DefaultProcess').show();
if (processes.indexOf(chosenValue) > -1)
$('#' + chosenValue + 'Process').show();
});
</script>
I was overthinking this.
$('#PhaseDD').change(function () {
var chosenValue = $(this).val();
$('.ProcessDD').hide();
if (chosenValue == "")
{
$('#DefaultProcess').show();
}
else
{
$('#' + chosenValue + 'Process').show();
}
});
I have a tablesorter table that is generated dynamically with javascript and ajax. There are inputs for the user to change values, and when they click a button to go to the next or previous record, it needs to save the information in the table to a MySQL table. I have looked at many of the posts on here and tried numerous examples, and I still can't get any of the data in the table to post to my PHP page to save it.
Here is a sample of the first row of my table:
$("#guides").append('<tr><td id="amCodeOld">'+data.amCodeOld+'</td><td><input type="text" class="qty" id="amOldQty"/></td><td>'+data.amOldPrice+
'</td><td>'+data.am+
'</td><td>'+data.amCodeNew+'</td><td><input type="text" class="qty" id="amNewQty"/></td><td>'+data.amNewPrice+
'</td><td><input type="checkbox" id="amS" '+
'"/></td><td><input type="checkbox" id="amR"'+'"/></td><td><input type="checkbox" id="amCall"'+
'"/></td><td><input type="text" id="amComm" value="'+
'"/></td></tr>');
There are more rows like this one, each for a different guide I am using. What I need to find is the value of the inputs with id of amOldQty, amNewQty etc, and the different checkboxes.
I have buttons for Next, Prev, and Print, and when the button is clicked I am trying to call a function called save() that will get the info, and send it via ajax to another PHP page to be saved.
save() looks like this:
function save() {
var amOldQty
$('#guides tr').each(function(){
alert("searching ");
amOldQty= $(this).find('#amOldQty').val();
if (amOldQty=='' || amOldQty== null) {
amOldQty = "Not Showing Number";
}
console.log(amOldQty);
});// END OF EACH FUNCTION
I have tried:
var amOldQty;
$('#guides tbody tr').each(function() {
amOldQty = $(this).find('td:nth-child(1) input').val();
});
console.log(amOldQty);
and the log shows undefined. I have also tried a more direct approach by using
$('#guides tbody tr').each(function() {
amOldQty = $(this).find('#amOldQty').val();
});
and still have nothing. I am getting the alert of Searching, but in the console.log(amQtyOld) all it shows me is "Not Showing a number". I have even tried to have the input populated when the table first is created, and it still does not find that number.
Update if I add td to:
$(guides tr td).each(function(){...
It does not even give me the alert of "Searching".
How do I get all the data out of this table so I can save it? it seems that everything I am trying should be working.
If your users use browsers that support contenteditable elements, then you can check out the contenteditable widget I have available for my fork of tablesorter.
If you don't want to use contenteditable elements, then you can try the following code (copied and modified from the contenteditable demo, but not tested)
var $table = $('table');
$table.children('tbody').on('change', 'input', function(event){
var $input = $(this),
$cell = $input.closest('td'),
newContent = $input.val(),
cellIndex = $cell[0].cellIndex, // there shouldn't be any colspans in the tbody
rowIndex = $this.closest('tr').attr('id'); // unique row id
// update tablesorter
$table.trigger("updateCell", [$cell]);
$.post("mysite.php", {
"row" : rowIndex,
"cell" : cellIndex,
"content" : newContent
});
});
Hopefully, you're also using an input parser for that column.
The final answer seems to be to just hardcode the value of the inputs $("#amOldQty:).val() and pass them as data through ajax to my php file to save the information. Here is the completed code in case anyone has a similar issue:
function save() {
function GuidesSave(){
this.update();
}
GuidesSave.prototype.list = ['am','fol','tich','book','neb','ster','c','byte','ing'];
GuidesSave.prototype.update = function(){
for( var i = 0 ; i < this.list.length ; i++ ){
var guide = this.list[i];
this[ guide + 'S' ] = $("#" + guide+'S' ).is(":checked") ? 1 : 0;
this[ guide + 'R' ] = $("#" + guide+'R' ).is(":checked") ? 1 : 0;
this[ guide + 'Call' ] = $("#" + guide+'Call' ).is(":checked") ? 1 : 0;
}// end of for loop
}
var guides = new GuidesSave();
$.ajax({
type: "POST",
url: "poSave.php",
dataType: "json",
data: ({po: $('#po').val(),isbn:$("#isbn13").val(),amOldQty:$("#amOldQty").val(),amNewQty:$("#amNewQty").val(),amS:guides.amS,amR:guides.amR, amCall:guides.amCall,amComm:$("#amComm").val(),

success: function(data){
}
});
}// END OF SAVE FUNCTION
The GuideSave function loops through all the check boxes (27 different ones) to see whichones are checked so I can save them as either a 1 or 0 and then have them checked or not when the record is recalled.
It is not really clear what or how you are wanting to present the data. However, here is a JSFiddle that does what it appears you desire.
The function createRowsForTesting() just creates the rows in the table and populates the <input> fields to make testing easier.
The function getDataFromTable() walks the rows of a <table>, or all <tables>, sending the data you said you wanted to the console. From your own answer to this question it became clear that you really wanted to access many more <input> elements than was mentioned in your question. Thus, this this function now builds an array of Objects which contain key:value pairs for the data in <input> fields. There is one Object in the array for each row. The array is returned to the calling function.
The function wrapGetDataFromTable() wraps getDataFromTable() providing the table ID, that we are only looking in rows within the <tbody> tag and that we want output to the console. The array returned by getDataFromTable() is output so we can see the data structure. The function is set up to run each time you press the [print to console] button.
For a table that looks like (with header row):
The output is:
amOldQty=amOldQty0_text amNewQty=amNewQty0_text amS=on amR=off amCall=off amComm=amComm0_text
amOldQty=amOldQty1_text amNewQty=amNewQty1_text amS=off amR=on amCall=off amComm=amComm1_text
amOldQty=amOldQty2_text amNewQty=amNewQty2_text amS=off amR=off amCall=on amComm=amComm2_text
The array of row input data objects is:
[0] Object { amOldQty="amOldQty0_text", amNewQty="amNewQty0_text", amS="on", more...}
amOldQty: "amOldQty0_text"
amNewQty: "amNewQty0_text"
amS: "on"
amR: "off"
amCall: "off"
amComm: "amComm0_text"
[1] Object { amOldQty="amOldQty1_text", amNewQty="amNewQty1_text", amS="off", more...}
amOldQty: "amOldQty1_text"
amNewQty: "amNewQty1_text"
amS: "off"
amR: "on"
amCall: "off"
amComm: "amComm1_text"
[2] Object { amOldQty="amOldQty2_text", amNewQty="amNewQty2_text", amS="off", more...}
amOldQty: "amOldQty2_text"
amNewQty: "amNewQty2_text"
amS: "off"
amR: "off"
amCall: "on"
amComm: "amComm2_text"

Note: The selector ($("#guides").append('<tr>...) used in your line to add the table row to the table might be your problem. It currently adds your rows as the last elements in the <table>, not the last in the <tbody>. While the browser should compensate for this, it is possible that it is not doing so in your environment. Try $("#guides tbody").append('<tr>...
However, it appears more likely that the issue is a header row (or a row without input cells) in the <tbody>. The code now accounts for this possibility.
Hi I have a table that was created in javascript, what I need to know is how to pass the values in row 1 or 2 into a aspx page using javascript with the click of a button:
here is my javascript code:
newContent += Hesto.Html.StartTR(item.CommonCable, 'lineInfoRow');
newContent += Hesto.Html.CreateTD('<input type="button" value="Print" id="btnprint" onclick="Redirect()">',null);
newContent += Hesto.Html.CreateTD(item.CommonCable, null, null);
newContent += Hesto.Html.CreateTD(item.Wire, null, null);
newContent += Hesto.Html.CreateTD(item.WireLength * 1000, null, 'centerAlign');
newContent += Hesto.Html.CreateTD(item.TerminalA, null, (sideFlag == 1 ? 'highlightOneSide' : (sideFlag == 3 ? 'highlightTwoSides' : 'highlightNone')));
newContent += Hesto.Html.CreateTD(item.SealA, null, (sideFlag == 1 ? 'highlightOneSide' : (sideFlag == 3 ? 'highlightTwoSides' : 'highlightNone')));
newContent += Hesto.Html.CreateTD(item.TerminalB, null, (sideFlag == 2 ? 'highlightOneSide' : (sideFlag == 3 ? 'highlightTwoSides' : 'highlightNone')));
newContent += Hesto.Html.CreateTD(item.SealB, null, (sideFlag == 2 ? 'highlightOneSide' : (sideFlag == 3 ? 'highlightTwoSides' : 'highlightNone')));
newContent = Hesto.Html.EndTR(newContent);
});
$('#AlternativeReworkCablesList').html(newContent);
}
here is my redirect page:
function Redirect() {
window.open ("http://10.19.13.67/ReworkLabels/Default.aspx","my window");
return false;
}
You have a few options: You could save the data in a cookie for re-use later, you could pass the data to the next page as a series of GET variables, or you could load the next page using AJAX so that your variables remain available.
Since you're using ASP, you could do something like this:
function Redirect() {
window.open ("http://10.19.13.67/ReworkLabels/Default.aspx?myVariable=" + myVariable,"my window");
return false;
}
To send big amount of data you can try this:
Create form with method post and action equal to url you want to redirect to (form can be hidden — it is not problem)
Create textarea/text field (not neccessary) in this form
Put your data in this textarea
Submit form via JS
Receive data on new page
Note, that javascript will escape data in this form. To unescape it use unescape() function.
