It's my first time trying to build something with angular , and i find myself not able to retrieve some JSON data.
The data is retrieve from a SQL database in JSON form then passed to a template thanks to angular route :
.when('/tasks/:TaskID',{
templateUrl: 'template/task_data_template.html',
controller:"showTaskData",
controllerAs: 'STD'
})
The showTaskData is defined as follow :
angular.module('moonDive').controller('showTaskData',function($http,$routeParams){
var store = this;
store.tasks= [];
json_Url = 'api/tasks_data.php?TaskID=' + $routeParams.TaskID;
$http.get(json_Url).success(function(data){
store.tasks = data;
})});
My Data have this structure :
This is accessible from the template html by :
{{STD.tasks[1]}}
Which return the data in that "JSON" way :
{
"ActionID": "1",
"Taskref": "1",
"Ast1_1": "",
"Ast2_1": "Start EVA watch\nopen hatch\nAssist CDR",
"Ast3_1": "",
"Ast1_2": "Egress cabin to LM porch\nReceive & jetttison bag\nReceive ETB/LEC",
"Ast2_2": "Deploy CDR PLSS antenna\nHand jettison bag to CDR\nHand ETB/LEC to CDR",
"Ast3_2": "",
"Ast1_3": "Descend lander to top rung\nUnlock and deploy MESA\nLower ETB on LEC",
"Ast2_3": "Tape recorder -off\nVerify voice signals level and uitlity floo [......]"
}
So far so good, so my final purpose is to have a table with two column (ast1 , ast2) and X row for X task. I'm not really sure how to begin , but i've tried something like that :
<table class="bordered hoverable responsive-table">
<tbody>
<tr ng-repeat="boo in STD.tasks[1]">
<td style=" color: blue;" ng-if="$odd"> {{boo}}</td>
<td style="color:red" ng-if="$even"> {{boo}}</td>
</tr>
</tbody>
</table>
Well no luck it doesn't work at all, but one weird thing that prevent me to understand what's going on is that it displays all the information but in what seems to be a random order.
I'd like to delete rows with "1" ; usually i would do a ng-if="boo.NameOfTheRow" ; but here i don't really have access to this name do I ?
So my question is : How to delete the unnecessary data? And how can I arrange my data by Astr1 and 2 (for the columns) and task 1 to X (for the rows)
Thanks a lot !
PS :
The generated code should look like that :
<table>
<thead>
<td> task </td>
<td> Astr 1 </td>
<td> Astr 2 </td>
<td> Astr 3 </td>
</thead>
<tbody>
<tr>
<td> 1</td>
<td> {{STD.tasks[1].Ast1_1}} </td>
<td> {{STD.tasks[1].Ast2_1}}</td>
<td>{{STD.tasks[1].Ast3_1}} </td>
</tr>
<tr>
<td> 2</td>
<td> {{STD.tasks[1].Ast1_2}} </td>
<td> {{STD.tasks[1].Ast2_2}}</td>
<td>{{STD.tasks[1].Ast3_2}} </td>
</tr>
<tr>
<td> 3</td>
<td> {{STD.tasks[1].Ast1_3}} </td>
<td> {{STD.tasks[1].Ast2_3}}</td>
<td>{{STD.tasks[1].Ast3_3}} </td>
</tr>
....
<tr>
<td> 7</td>
<td> {{STD.tasks[1].Ast1_7}} </td>
<td> {{STD.tasks[1].Ast2_7}}</td>
<td>{{STD.tasks[1].Ast3_7}} </td>
</tr>
</tbody></table>
Thus the data should be displayed as :
If your STD.tasks is an array of entries, then you need to simply change your ng-repeat to ng-repeat="boo in STD.tasks".
You should be getting back JSON data in array form:
[
{"field":"value", "field2": "value"},
{"field":"value", "field2": "value"},
{"field":"value", "field2": "value"},
...
]
ng-repeat will want to iterate over each of those values in the array. Right now, you've pointed it to the very first item in the array, so it's repeating over each property in the object.

i have a JSON-datafile of typ: trip. In trip is a object: driver (with name, id etc..).
{
"id": "1",
"gpsStart": "N50.418716° , E006.750000°",
"gpsEnd": "N50.318516° , E006.750000°",
"tripBuinsness": true,
"startOdometer": 25698,
"endOdometer": 25700,
"wayPoints": [
"N50.418716° , E006.750000°",
],
"driver": [{
"name": "Theo"
}]
}
How can I refer the driver name in html?
<tbody>
<tr *ngFor="let trip of trips">
<td>{{trip.projectName}}</td>
<td>{{trip.driver}}</td>
</tr>
</tbody>
You do not need ngFor over trip since its an Object, change it over trip.driver which is an array of Objects,
<tbody>
<tr *ngFor="let driver of trip.driver">
<td>{{driver.name}}</td>
</tr>
</tbody>
If you want the only the first driver you can access him through the 0th index:
<tbody>
<tr *ngFor="let trip of trips">
<td>{{trip.projectName}}</td>
<td>{{trip.driver[0].name}}</td>
</tr>
</tbody>
But if you want all of the drivers add another ngFor loop to your template:
<tbody>
<tr *ngFor="let trip of trips">
<td>{{trip.projectName}}</td>
<td>
<span *ngFor="let d of trip.driver">{{d.name}} </span>
</td>
</tr>
</tbody>
'driver' is an array. I think you can access the name by doing trip.driver[0].name or iterating over trip.driver.
Let's say I have a simple table like this one:
<tbody>
<tr>
<td> A </td>
<td> B </td>
<td> C </td>
<td><input type="button"></td>
</tr>
<tr>
<td> 1 </td>
<td> 2 </td>
<td> 3 </td>
<td><input type="button"></td>
</tr>
What I'm trying to do is, when I click the button a function takes place which gets the first character in the first table row. So in row 1 that would be "A", in row 2 that would be "1". None of the rows or cells have unique ID's, so can't use those.
Right now I was trying to do something like:
charValue = $(this).parent()first().text();
But for some reason when I do that I get "ABC" and not just "A".
Thanks in advance!
Use find after closest("tr")
$(this).closest("tr").find("td").first().text();
Or alternatively td:first
$(this).closest("tr").find("td:first").text();
Simply use this code
$("input").click(function() {
// Bad practice
//var charValue = $(this).parent().parent().children().first().text();
//god practice
var charValue = $(this).closest("tr").find("td:first").text();
alert(charValue)
})
I need one help i need to display data inside table using Angular.js.I am explaining my code below.
$scope.listOfData=[
{
{'date':'2016-01-25 18:14:00','name':'raj','email':'raj#gmail.com','order_status':1,'order_id':1111},
{'date':'2016-02-04 11:26:05','name':'raj','email':'raj#gmail.com','order_status':0,'order_id':2222}
},
{
{'date':'2016-01-23 13:15:59','name':'rahul','email':'rahul#gmail.com','order_status':1,'order_id':3333},
{'date':'2016-01-25 18:14:00','name':'rahul','email':'rahul#gmail.com','order_status':0,'order_id':4444}
}
]
my html table is given below.
<div class="table-responsive dashboard-demo-table">
<table class="table table-bordered table-striped table-hover" id="dataTable" >
<tbody>
<tr>
<td rowspan="2">Date</td>
<td rowspan="2">Name</td>
<td rowspan="2">Email</td>
<td colspan="7">Order</td>
</tr>
<tr>
<td>Order Id</td>
<td>Order status</td>
</tr>
<tr>
<td>date</td>
<td>name</td>
<td>email</td>
<td>orderid</td>
<td>orderstatus</td>
</tr>
</tbody>
</table>
</div>
expected output result.
date name email order
order_id order_status
2016-01-25 raj raj#gmail.com 1111 1
to 2016-02-04 2222 0
The above table is for serial no-1 again for sl no-2 the data will display accordingly.
Here i need suppose 0th index of $scope.listOfData has two set of data some field value like name,email are same so these two sate of data will join and it will display in 1st index of the table.Here date column will contain lower date to higher date like(from date to todate),name and email filed will contain the value one but here different is for order column order_id and order_status is different for each set of data of 0th index from $scope.listOfData so these will again move in a another loop.Please help me.
The following may help you
<div ng-repeat="data in listOfData">
<!--<Do whatever you need here with data.name, data.date etc...>-->
<!--You can keep your table here.-->
</div>
<tr ng-repeat="data in listOfData">
<td>{{data.date}}</td><td>{{data.name}}</td>....
</tr>
PS for header you can use a <thead> tag
Edit :
{
{'date':'2016-01-25 18:14:00','name':'raj','email':'raj#gmail.com','order_status':1,'order_id':1111},
{'date':'2016-02-04 11:26:05','name':'raj','email':'raj#gmail.com','order_status':0,'order_id':2222}
}
You can't with your json format like this, flatten it in a one level array with even index containing "from" and odd containing "to" datas then do the following
<tr ng-repeat="data in listOfData">
<td ng-if="$index %2==0">{{data.date}}</td>
<td ng-if="$index %2==1">To {{data.date}}</td>
...
</tr>
EDIT : can't really make a plunker, here is what by flatten I mean transform this
$scope.listOfData=[
[
{'date':'2016-01-25 18:14:00','name':'raj','email':'raj#gmail.com','order_status':1,'order_id':1111},
{'date':'2016-02-04 11:26:05','name':'raj','email':'raj#gmail.com','order_status':0,'order_id':2222}
},
{
{'date':'2016-01-23 13:15:59','name':'rahul','email':'rahul#gmail.com','order_status':1,'order_id':3333},
{'date':'2016-01-25 18:14:00','name':'rahul','email':'rahul#gmail.com','order_status':0,'order_id':4444}
]
]
Into this :
$scope.listOfData=[
{'date':'2016-01-25 18:14:00','name':'raj','email':'raj#gmail.com','order_status':1,'order_id':1111},
{'date':'2016-02-04 11:26:05','name':'raj','email':'raj#gmail.com','order_status':0,'order_id':2222},
{'date':'2016-01-23 13:15:59','name':'rahul','email':'rahul#gmail.com','order_status':1,'order_id':3333},
{'date':'2016-01-25 18:14:00','name':'rahul','email':'rahul#gmail.com','order_status':0,'order_id':4444}
}
]
So your "from" lines will have even index (0,2,4...) and your "to" lines will have the odds ones (1,3,5,...).
Using $index you can now built properly your lines : $index is given by ng-repeat. ng-if is a directive that won't build the dom element if the condition is not true.
So this
<td ng-if="$index %2==0">{{data.date}}</td>
<td ng-if="$index %2==1">To {{data.date}}</td>
Will always build only one <td> element.
in the client side, I have a json object which I receive from REST service somewhere. This object has more that one attribute, one of them is a String array. I want some assistance on how to print this array using angular JS code embedded within html.
this is my JSON object:
[
"title": "Developing a System for Information Management in Disaster Relief",
"url": "http://scholar.google.com/scholar",
"relatedTitles":
[
"Distributed robotic sensor networks",
"Improving information access for emergency",
"Tangible and wearable user interfaces for",
"Non-parametric inferenc",
"Airborne near-real-time monitoring of assembly"
]
]
and here is how the html ng-repeat looks like.
<tr ng-repeat="publication in publications">
<td>{{publication.title}}</td>
<td>{{publication.url}}</td>
<td>{{publication.relatedTitles}} </tr>
Note:"publications" is the JSON object name
It depends on how you want to print it. If you want it like and array, joined with commas for example use this html code:
<tr ng-repeat="publication in publications">
<td>{{publication.title}}</td>
<td>{{publication.url}}</td>
<td>{{publication.relatedTitles.join(', ')}}
</tr>
Else, if you want with a <span> tag each for example, you can do another ng-repeat:
<tr ng-repeat="publication in publications">
<td>{{publication.title}}</td>
<td>{{publication.url}}</td>
<td>
<span ng-repeat="relatedTitle in publication.relatedTitles">
{{publication.relatedTitles}}
</span>
</td>
</tr>
You can nest ng-repeat's
So you should be able to do something like this:
<tr ng-repeat="publication in publications">
<td>{{publication.title}}</td>
<td>{{publication.url}}</td>
<td>
<table>
<tr ng-repeat="title in publication.relatedTitles">
<td>{{title}}</td>
</tr>
</table>
</td>
</tr>
<tr ng-repeat="publication in publications">
<td>{{publication.title}}</td>
<td>{{publication.url}}</td>
<td>
<span ng-repeat="title in publication.relatedTitles">
{{title}}<br>
</span>
</td>
</tr>
Why doesn't this simple table structure work in angularjs? None of the rows gets populated with the data. If I replace span with tr, it works fine but my third column of Percent doesn't fit in well.
<table class="table table-hover">
<tbody>
<tr>
<th>Grade</th>
<th>Point</th>
<th>Percent</th>
</tr>
<tr>
<span ng-repeat="gdata in gradepoints">
<td ng-repeat="(grade, gp) in gdata"> {{grade | uppercase}} </td>
<td ng-repeat="(grade, gp) in gdata"> {{gp}} </td>
</span>
<span ng-repeat="pdata in percents">
<td ng-repeat="(grade, perc) in pdata"> {{perc}} </td>
</span>
</tr>
</tbody>
</table>
Try this:
<tr ng-repeat="gdata in gradepoints">
<td>{{gdata.grade | uppercase}}</td>
<td>{{gdata.gp}}</td>
<td>{{pdata[$index].perc</td>
</tr>
You want one row for each element in the gdata array, so the ng-repeat needs to be on the <tr> element. If the two arrays aren't in sync, you can create a function in your controller to return the pdata element you need:
$scope.findPdata(gdata, index) {
// ... do your magic here to find the pdata element you want
return result;
}
<td>{{findPdata(gdata, $index)}}</td>
guessing from the below:
<tr>
<th>Grade</th>
<th>Point</th>
<th>Percent</th>
</tr>
i guess your table has 3 columns so your each row has 3 columns?
in that case use the following
<tr ng-repeat="gdata in gradepoints">
<td>{{gdata.grade | uppercase}}</td>
<td>{{gdata.gp}}</td>
<td>{{gdata.percent}}</td>
</tr>
for above to work your gradepoints must be an ARRAY containing objects with 3 properties each i.e. grade,gp,percent
