element.val() returning previous value

Here is my problem
I am trying to create a button that calls a directive function which then activates the google place 'place_changed' event that is assigned to the directive. If the getPlace() function doesn't return a result e.g. var result = scope.gPlace.getPlace(); then I want force a place prediction by doing the following.
if( result === undefined ) {
result = { name: element.val() }
}
however the problem is that this code will work when the page is first loaded but subsequent attempts will assign the var result to the previous text that was entered. e.g. Type "Adelaide" and click on the button equals successful process however now type melbourne and click on the button will still equal "Adelaide"

Why are you using element.val() when you have an ngModel bound to the input? Why not use scope.ngModel instead?

Angular JS dual input Directive UpDate View Value

Hi I have a situation here,
I have created a dual input directive. Can you please help to in the below scenario.
When I change the model value via controller to undefined, the view values are not cleared. Here is the Codes,
My Dual Input Directive is as follows,
angular.module("awcQuoteBuy.directives")
.directive('dualInput', function($timeout, inputValidationService) {
return {
restrict: 'E',
templateUrl: 'app/partials/common/doubleInput.html',
scope: {
modelValue: '=',
size: '#',
fieldError: '#',
blurFn: '&loseFocus'
},
link: function postLink(scope, element, attrs, ctrl) {
scope.leftFocused = false;
scope.rightFocused = false;
scope.$watch('left', function(newVal, oldVal) {
if (newVal!==oldVal) {
var tmp = (newVal) ? inputValidationService.formatNumber(newVal+'') : '';
scope.modelValue = tmp + '|'+ scope.getOtherValue(scope.right);
}
});
scope.$watch('right', function(newVal, oldVal) {
if (newVal!==oldVal) {
var tmp = (newVal) ? inputValidationService.formatNumber(newVal+'') : '';
scope.modelValue = scope.getOtherValue(scope.left) + '|' + tmp;
}
});
scope.getOtherValue = function(value) {
return (value && value!=='') ? inputValidationService.formatNumber(value+'') : '';
};
//will set the value initially
$timeout(function() {
if (!scope.modelValue || scope.modelValue===null) {
scope.modelValue = '';
}
if (scope.modelValue!=='') {
var splitIndex = scope.modelValue.indexOf('|');
if (splitIndex>=0) {
var values = scope.modelValue.split('|');
scope.left = values[0];
scope.right = values[1];
} else {
scope.left = scope.modelValue;
}
}
});
/*
Below functions will add on-blur (lose focus) support to both fields.
*/
scope.focusLeft = function() {
scope.leftFocused = true;
};
scope.blurLeft = function() {
scope.leftFocused = false;
$timeout(function() {
if (!scope.rightFocused) {
scope.blurFn();
}
}, 100);
};
scope.focusRight = function() {
scope.rightFocused = true;
};
scope.blurRight = function() {
scope.rightFocused = false;
$timeout(function() {
if (!scope.leftFocused) {
scope.blurFn();
}
}, 100);
};
}
};
});
The HTML Piece of code is as follows,
<dual-input model-value="dualInput[$index]" ng-switch-when="DUAL_NUMBER" size="{{q.length}}"
field-error="{{q.invalid || (nextClicked && !validateGeneralQuestion(acc.memberId, q))}}" id="{{'gQDual'+$index}}"
lose-focus="saveGeneralAnswer(acc.memberId, q)"></dual-input>
In My Controller when I set the scope value to undefined or null, the entered values in the view is not cleared. Please help me here what I should do to clear this value
$scope.dualInput[$index]=undefined;

The directive itself has got the auto initialize feature. So I had to re render the directive whenever I wanted to reinitialize.
If you want to explicitly update user ctrl.$setViewvalue = ""

Jquery Auto-Complete Limited Search Results (JSON)

I'm using the FoxyComplete plugin with Jquery Auto-Complete to do a simple search. Everything is setup and working great but I'm finding the search results extremely limiting.
I use a big JSON file for all of my data and the problem I'm having is in the following case: Let's assume that my JSON file has the following description:
{
"title": "Brand new black car"
},
If a user searches "black car", he or she will get the result perfectly and the search is great. BUT, if a user search "car new", nothing comes up even though both keywords are in my JSON file.
Any help would be great. I poured through the Jquery AutoComplete docs and couldn't find a solution either. My Jquery autocomplete js is below:

Slickgrid, column with a drop down select list?

Hi I was wondering if anyone knows if it's possible to define a column in slickgrid as being a drop down select list. If not does anyone with some experience with slickgrid know how I should go about adding this option?
Thanks

You probably dont want to make a new select editor for each range of options. Also you may not know that range of all option value beforehand.
In that case you want a flexible range of options in a select type editor. In order to do this you can add an extra option to your column definitions (e.g. called options) like this:
var columns = [
{id:"color", name:"Color", field:"color", options: "Red,Green,Blue,Black,White", editor: SelectCellEditor},
{id:"lock", name:"Lock", field:"lock", options: "Locked,Unlocked", editor: SelectCellEditor}
]
and access that using args.column.options in the init method of your own SelectEditor object like this:
SelectCellEditor : function(args) {
var $select;
var defaultValue;
var scope = this;
this.init = function() {
if(args.column.options){
opt_values = args.column.options.split(',');
}else{
opt_values ="yes,no".split(',');
}
option_str = ""
for( i in opt_values ){
v = opt_values[i];
option_str += "<OPTION value='"+v+"'>"+v+"</OPTION>";
}
$select = $("<SELECT tabIndex='0' class='editor-select'>"+ option_str +"</SELECT>");
$select.appendTo(args.container);
$select.focus();
};
this.destroy = function() {
$select.remove();
};
this.focus = function() {
$select.focus();
};
this.loadValue = function(item) {
defaultValue = item[args.column.field];
$select.val(defaultValue);
};
this.serializeValue = function() {
if(args.column.options){
return $select.val();
}else{
return ($select.val() == "yes");
}
};
this.applyValue = function(item,state) {
item[args.column.field] = state;
};
this.isValueChanged = function() {
return ($select.val() != defaultValue);
};
this.validate = function() {
return {
valid: true,
msg: null
};
};
this.init();
}

I assume you mean a custom cell editor.
Here's a sample select-based boolean cell editor from slick.editors.js. You could easily modify it to work with an arbitrary set of possible values.
function YesNoSelectCellEditor($container, columnDef, value, dataContext) {
var $select;
var defaultValue = value;
var scope = this;
this.init = function() {
$select = $("<SELECT tabIndex='0' class='editor-yesno'><OPTION value='yes'>Yes</OPTION><OPTION value='no'>No</OPTION></SELECT>");
if (defaultValue)
$select.val('yes');
else
$select.val('no');
$select.appendTo($container);
$select.focus();
};
this.destroy = function() {
$select.remove();
};
this.focus = function() {
$select.focus();
};
this.setValue = function(value) {
$select.val(value);
defaultValue = value;
};
this.getValue = function() {
return ($select.val() == 'yes');
};
this.isValueChanged = function() {
return ($select.val() != defaultValue);
};
this.validate = function() {
return {
valid: true,
msg: null
};
};
this.init();
};

If your cell already contains a "select"-tag with multiple options, you can extract this html from the args. The approach differs from the previous answers, but I was personally troubled with these solutions, course my cell already contained a select-tag. I'd like to reuse this cell instead of reconstructing it completely in the this.init. Likewise, I'd like to keep using the same options, as my existing select already have, instead of parsing them to the var column = { ...
The $( args.item[ args.column.field ] ) return the active cells content, which basically just get re-appended to the the container (the cell-object). From if ( document.createEvent ) and down, is just a functionality which automatically opens the dropdown on activation; etc. when you use tabulator to navigate to the cell.
function SelectCellEditor( args ) {
var $select;
var defaultValue;
var scope = this;
this.init = function () {
$select = $( args.item[ args.column.field ] );
$select.appendTo( args.container );
$select.focus();
// Force the select to open upon user-activation
var element = $select[ 0 ];
if ( document.createEvent ) { // all browsers
var e = new MouseEvent( "mousedown", {
bubbles: true,
cancelable: true,
view: window
});
element.dispatchEvent( e );
} else if ( element.fireEvent ) { // ie
element.fireEvent( "onmousedown" );
}
};
}
