Get child element without id or class attributes with AngularJS

I have the following HTML code :
<div id="someId">
<div ng-transclude>
</div>
</div>
Really simple I am getting the div element which has ID attribute using the following function :
var getElementById = function (id) {
return angular.element("#" + id);
};
Where in this example case the ID is 'someId'. My goal is to get the div inside the one I just got. So I want to return the div with ng-transclude attribute. I believe that this will happen by getting an element by attribute name or something.
Thanks in advance.
PS: I can't put any other attributes in the div I wanted(like id) because in the real life it is far more complecated and the code is auto-generated.

I think this will help you
var getElementByAttribute = function (attribute) {
return angular.element(document).find('[' + attribute + ']');
};
var el = getElementByAttribute('ng-transclude')

I don't know if that will be the Angular way, but you can use native properties of the HTML element. Something like this:
var getElementById = function (id) {
return angular.element("#" + id);
};
var childDivWithTransclude = getElementById('someId').children[0];

Jquery add data to html before adding to DOM

I am building html on the fly need to add data before I add it to DOM. Since I am looping thru' lot of information, I would like to add the relevant data info along with the dom I am building instead of adding the html and then looping thru again to add the data.
result.forEach(function(record) {
html += '<div id ="' record.ID + '">test content </div> ';
//add data to above
});
I can do another loop here after adding it to DOM
$(body).append(html);
testresult.forEach(function(record) {
$("#" +record.ID).data(record);
});

Instead of concatenating strings to piece together your HTML, you may way to try something like this:
result.forEach(function(record) {
$('.selector').append(function () {
var $div = $('<div></div>');
$div.attr('id', record.testID).text('some text');
return $div;
});
});
This creates a new div jquery object for each item in result. You can use the record object to add attributes, data, text, etc to you object. It will be added the DOM when the callback passed into .append returns your new jquery DOM object.

Start trying to use jQuery to create your html elements so you can take fully advantage of jQuery and its plugins.
Ex:
var div = $("<div></div>") // create the element
.text("test content") // change the inner text
.attr("id", record.testID); // set the element id
div.appendTo("body");
You can check out [http://www.w3schools.com/jquery/] as a great source for learning jQuery.

You have quotes problem in the following line :
html += '<div id =record.testID' + '>test content </div> ';
________^______________________^___^_____________________^
You should fix that using double quotes because as it's now the string will be considered as '<div id =record.testID'.
html += '<div id="'+record.testID+'">test content </div>';
Or you could use separated definition :
$.each(result, function(index,record) {
var div = $('<div>test content</div>');
div.attr('id', record.testID);
div.data('test', record.testDATA);
$('body').append(div);
})
Hope this helps.
var result = [{testID: 1,testDATA: 'data 1'},{testID: 2,testDATA: 'data 2'},{testID: 3,testDATA: 'data 3'}]
var html='';
$.each(result, function(index,record) {
var div = $('<div>test content</div>');
div.attr('id', record.testID);
div.data('test', record.testDATA);
console.log(div.data('test'));
$('body').append(div);
})

Table setVisible error

I am trying to hide a table on my HTML page. So I use oTable.setVisible(false). This works fine, i.e my table is hidden but I get the text in place of table as shown below in the picture. Is there any way to not display that or any reason why is it been displayed?
I paste below my code and also the picture for reference.
View.js
var oModel = new sap.ui.model.odata.ODataModel( "../TEST_ODATA.xsodata",true);
oTable.setModel(oModel);
oTable.bindRows("/sPath");
var oButton1 = new sap.ui.commons.Button({
text : "click",
style: sap.ui.commons.ButtonStyle.Accept,
press : function() {
document.getElementById("table").innerHTML = oTable.setVisible(false);
}});
index.html
<body class="sapUiBody">
<div id="table" style="margin-bottom: 20px"></div>
</body>
Error:

This should just do it (no need for setting the innerHTML) :
press : function() {
oTable.setVisible(false);
}

just set your table to setVisible(false) and invalidate it so that ui5 will rerender it.
this should be enough.
oTable.setVisible(false);
oTable.invalidate();
and remove your:
document.getElementById("table").innerHTML = ...

I have no idea what sapui5 is or where oTable comes from, but it looks like your problem is here:
document.getElementById("table").innerHTML = oTable.setVisible(false);
You're setting the HTML inside the #table element to the return value of of the setVisible method.
I imagine you want one (or both) of:
document.getElementById("table").innerHTML = '';
oTable.setVisible(false);
Recommendation if you want to hide an element would be to style it as such:
document.getElementById("table").className = 'hidden';
and:
.hidden { display: none; }
Or if you want to remove an element:
var table = document.getElementById("table");
table.parentNode.removeChild(table);

use this
document.getElementById("table").style.display = "none";
instead of this:
document.getElementById("table").innerHTML = oTable.setVisible(false);

JQuery get calling <script> tag when dynamically loaded

How can I locate the tag which calls a JQuery script, when
the tag is dynamically loaded, so won't be the last
tag on the page?
I'm using the MagicSuggest autosuggest library. I want to give certain suggested items a different background color depending on their contents, which I'm currently doing by adding JQuery inside a tag, which I'm adding on to the String which is returned to be rendered inside the selection div. Then, to get the div the item is suggested in, I need to essentially get the parent() of the tag, and change it's css() properties. How can I get this current script tag however?
I'm currently assigned each new tag an id generated from incrementing a JS variable - which works, but isn't very 'nice'! Is there anyway I can directly target the tag with JQuery?
If it perhaps makes it clearer, here is my current selectionRenderer function.
selectionRenderer: function(a){
var toRet = a.english;
var blueBgScript = "<script id=ft" + freeTextFieldID + ">$('#ft" + freeTextFieldID + "').parent().css('background', 'blue');</script>"
if(a.id==a.english){
toRet += blueBgScript;
freeTextFieldID++;
}
return toRet;
},

Why don't you add some code at afterrender event instead? Add some tag to flag the options that need a different background, then detect the parents and add a class (or edit the bg property) or whatever you like:
var newMS = $('#idStr').magicSuggest({
data: 'states.php',
displayField: 'english',
valueField: 'id',
selectionRenderer: function(a){
var toRet = a.english;
if(a.id==a.english) toRet = "<span class='freetext'>" + toRet + "</span>";
return toRet;
},
});
$(newMS).on('selectionchange', function(event,combo,selection){
var selDivs = $(event.target._valueContainer[0].parentNode).children('div'); //Get all the divs in the selction
$.each(selDivs,function(index,value){ //For each selected item
var span = $(value).children('.freetext'); //It if contains a span of class freetext
if(span.length == 1) $(value).css('background','blue'); //Turn the background blue
});

Alternative writing method to create DOM elements and append

If I want to append a button with my pic to the document, I would write:
$('#story_pages').append('<div><button value="'+window_value+'" onclick="reload_to_canvas(this.value)" > <img id= "w'+window_value+'", src="../pic/white_img.png", width="110px", height="110px"/> </button></div>');
It's too long and hard to debug. But how can I create an img tag, then wrapping it with a button tag and div tag...
Please suggest any clear and simple method with jQuery's help.
UPDATE:
story_pages is the jQuery UI dialog's id. I don't know if it affects or not.
UPDATE:
I found the problem. I want the image shown above on the button instead of a button and a image.
The script you give me will result this:
<div>
<button value="1"></button>
<img ......./>
</div>
The img tag has to be wrapped by button tag like:
<button>
<img.../>
</button>
So the image will attach on the button.

How about this:
var $button = $('<button>', {
value: window_value,
click: function() { reload_to_canvas(this.value); }
});
var $img = $('<img>', {
id : 'w'+ window_value,
src: '../pic/white_img.png'
})
.css({ height: '100px', width: '100px'});
$('#story_pages').append($('<div>').append($button, $img));

If a string is passed as the parameter to $(), jQuery examines the string to see if it looks like HTML (i.e., it starts with ). If not, the string is interpreted as a selector expression, as explained above. But if the string appears to be an HTML snippet, jQuery attempts to create new DOM elements as described by the HTML. Then a jQuery object is created and returned that refers to these elements.
try this
var div=$('<div>'); // creates new div element
//updated here
var img = $('<img />') .attr({ // create new img elementand adds the mentioned attr
id:'w'+window_value ,
src:"../pic/white_img.png",
width:"110px",
height:"110px"});
var button= $('<button/>', //creates new button
{
value: window_value, //add text to button
click: function(){ reload_to_canvas(this.value)} //and the click event
}).html(img); /// and <-- here... pushed the created img to buttons html
div.append(button); //append button ,img to div
$('#story_pages').append(div); //finally appends div to the selector
updated example fiddle

$('#story_pages').append(
$('<div>').append(
$('<button>', {
value : window_value
}).click(function() {
reload_to_canvas(this.value);
}).append(
$('<img>', {
id : 'w' + window_value,
src : '../pic/white_img.png'
}).width(110)
.height(110)
)
)
);
