javascript - Filtering array of objects with multiple attribute on multiple condition -


i trying filter array of objects multiple attribute on multiple condition. i'm creating param array consists of of multiple array holding parameters. example

var params = [     ["id", "equals", "11060"],     ["user_id", "exact", "84"] ];

first element key , second 1 condition , third 1 value. first filtering condition id == '11060' , second 1 user_id = '84'

// data filter     var originaldata = [{         "id": 11141,         "user_id": 84,         "received": "26 jan 2017",         "approvalstatus": "approved"     }, {         "id": 11080,         "user_id": 84,         "received": "25 jan 2017",         "approvalstatus": "approved"     }, {         "id": 11079,         "user_id": 84,         "received": "25 jan 2017",         "approvalstatus": "approved"     }, {         "id": 11078,         "user_id": 84,         "received": "25 jan 2017",         "approvalstatus": "approved"     }, {         "id": 11060,         "user_id": 84,         "received": "24 jan 2017",         "approvalstatus": "approved"     }];

following filtering function.

   filtereddata = originaldata.filter(function(item) {         params.foreach(function(value, index) {             var cond = value[1];             var ckey = value[0];             var cvalue = value[2];             var flag = false;             if (cond == 'equals') {                 if (item[ckey] == number(cvalue)) {                     flag = true;                 }             } else if (cond == 'exact'){                 if (item[ckey].tostring() == cvalue) {                     flag = true;                 }             }             return flag;         });         return false;     });

but it's not working. doing wrong? tia.

jsfiddle

you foreach(), return value not transmitted return value of filtering function. also, didn't decided if value must pass test or one. assume it's test must passed successfully. if it's 1 of them, code different.

filtereddata = originaldata.filter(function(item) {     var i, ntest, ckey, cvalue, flag;     for(i=0, ntest=params.length; i<ntest; ++i) {         ckey = params[i][0];         cvalue = params[i][2];         switch(params[i][1]) {             case "equals":                 if(item[ckey] != number(cvalue)) return false;             break;             case "exact":                 if(item[ckey].tostring() != cvalue) return false;             break;         }     }     return true; });

python - How to insert QWidgets in the middle of a Layout? -

i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
