javascript - How to take value from input and take it to AJAX request link? -

so have done ajax request angularjs: http://jsfiddle.net/c0lkja0h/1/ when use link example $http.get('http://api.wunderground.com/api/key/forecast/geolookup/conditions/q/san_francisco.json') (without '+ city +' in link) works great. when add variable, add ng-model="city" , hit submit, says city not defined how can make take city name input , use in newajaxreq function when click "find weather" button ? cool default link static link (when person first visited site), , after city taken input if user wants. thanks! there couple of things wrong approach. don't name controller. should anonymous function take parameters modules want inject, such .controller(function($http){ //do }); or .controller(['$http',function($http){ //do }]) avoid losing reference variables when minify js files. inside controller, define function want takes parameter city, such $scope.sendajax = function(city){ //do } . in view gonna call

say have 2 images , want place them side side few spaces between them, how do that? heard float? , how can/would use it? usually images behave floating left, nicael pointed out, can place them next each other. or can use style="float:left;" stated in first answer. on other hand, image element has nice align attribute, allows manipulation in way: <p>some text above</p> <img src="http://urlref.at/images/3o.gif" align="left" /> <img src="http://urlref.at/images/3o.gif" align="left" /> <img src="http://urlref.at/images/3o.gif" /> <p>some text underneath</p> then not put align left in last image text goes underneath , not next image. to space image can use vspace , hspace attributes: <p>some text above</p> <img src="http://urlref.at/images/3o.gif" align="left" hspace="20" /> <img src="http://urlref.at/images/3o.

this question has answer here: how sort std::vector values of different std::vector? 12 answers give 2 integer vectors in c++ (same size), i'd sort 1 of vectors smallest largest element , change order of second vector respectively. how can achieve without using boost library? thanks. you can restructure code that, instead of 2 vectors of integers, uses vector of s , s structure containing 2 integers. can define specific operator< used sort function. this has advantage strict coupling between 2 sets of data stated in way stored.
