Trying to open random pages through casperJS start method but some pages are loading properly and some of them are not, so in this scenario it is not exiting from casperjs.
It is getting stuck in console then need to manually exit from console using CTR+C.
casper.start("some url", function() {
if(this.status().currentHTTPStatus == 200) {
casper.echo("page is loading");
} else {
casper.echo("page is in error ");
this.exit();
}
});
Wrap it by a then step with a global stepTimeout option.
Sample code:
var casper = require('casper').create({
stepTimeout: 10000 //10s
})
casper.start()
casper.then(funtion(){
casper.open(url)
})
casper.run()
Try bypass() to ignore the next thens.
casper.start("some url", function() {
if(this.status().currentHTTPStatus == 200) {
casper.echo("page is loading");
} else {
casper.echo("page is in error ");
this.bypass(2); // Will not execute the then functions.
}
}).then(function() {
// The 1st then function.
}).then(function() {
// The 2nd then function.
})
casper.run(function() {
this.echo('Something');
this.exit(); // <--- Here.
});

I have the following code, which works fine except for the "makeToast" function that I'm trying to call when status response is true. I get a "this.makeToast is not a function" error on the console.
This function is working fine if I call it after the XMLHttpRequest code. The data is also not being assigned to the msgForm property. I could not figure out why. The "alert(..." message work fine.
<script>
import ToastMixins from '/src/mixins/ToastMixins'
let config = {
headers: {
}
}
export default {
name: 'ModalDestaque',
mixins: [
ToastMixins
],
methods: {
myFunction() {
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
console.log('onreadystatechange');
console.log('responseText 1', xhr.responseText);
this.loading = false;
if (xhr.status == 200) {
console.log('responseText 2', xhr.responseText);
let responseObj = JSON.parse(xhr.responseText);
console.log('responseObj', responseObj);
if (responseObj.status == true) {
//alert('Ok');
// this is not working:
this.msgForm = "Message success!";
this.makeToast('b-toaster-bottom-right', true, 'success');
} else {
alert('Not ok...');
}
}
}
};
}
}
}
What am I doing wrong?
I've found the solution while reading the docs at W3 Schools.
W3 Schools AJAX XMLHttp - Multiple Callback Functions
Although, I haven't found a working example anywhere.
In my code, at the button click event that triggers the XMLHttpRequest, I've added the function name "callToast" as a variable, so:
#click="onClickSubmit(myValue, myId, myTitle, callToast)"
Then in the script:
<script>
onClickSubmit(amount, id, title, cFunction) {
// stuff
if (xhr.status == 200) {
let responseObj = JSON.parse(xhr.responseText);
if (responseObj.status == true) {
// here I call the callToast function:
cFunction(this);
alert('Ok');
} else {
alert('Not ok...');
}
}
},
callToast() {
this.msgForm = "Message success!";
this.makeToast('b-toaster-bottom-right', true, 'success');
}
</script>
I have the following bit of code:
Which prints the following in the console:
I've been bashing my head for a very long time, not sure where to go from here. It was working just fine when I pushed last. Then, I made some changes which broke it as you can see. To try to fix it, I stashed my changes, but I'm still getting this error.

search: throttle(live => {
let vm = this;
console.log("entered!!!");
console.log("this", this);
console.log("vm", vm);
if (typeof live == "undefined") {
live = true;
}
if (!live) {
// We are on the search page, we need to update the results
if (vm.$route.name != "search") {
vm.$router.push({ name: "search" });
}
}
vm.$store.dispatch("search/get", {
type: vm.searchType,
query: vm.searchQuery
});
}, 500)
Assuming search is in your methods it should not be using an arrow function as that will give you the wrong this binding.
Instead use:
methods: {
search: throttle(function (live) {
// ...
}, 500)
}
Here I'm also assuming that throttle will preserve the this value, which would be typical for implementations of throttling.
Like I said in my comment, I suspect this is a scoping issue.
Perhaps if you return the throttle function with the Vue component passed in, you might see better results:
search: function() {
let vm = this;
return throttle(live => {
console.log("entered!!!");
console.log("this", this);
console.log("vm", vm);
if (typeof live == "undefined") {
live = true;
}
if (!live) {
// We are on the search page, we need to update the results
if (vm.$route.name != "search") {
vm.$router.push({ name: "search" });
}
}
vm.$store.dispatch("search/get", {
type: vm.searchType,
query: vm.searchQuery
});
}, 500)
}
I'm a newbie at ExtJs and I'm struggling to figure out how to use callback functions in ExtJs. The ExtJs version I'm using is 4.2.1
Basically I want to chain the execution of 2 functions:
func1: function() {
}
func2: function() {
}
so that func2() only starts executing after func1() completes.
From what I've read so far, I need to use callback function, but for the life of me I cannot get it.
Here Is my code:
filter: function (filters, value) {
if (Ext.isString(filters)) {
filters = {
property: filters,
value: value
};
}
var me = this,
decoded = me.decodeFilters(filters),
i = 0,
length = decoded.length;
for (; i < length; i++) {
me.filters.replace(decoded[i]);
}
Ext.Array.each(me.filters.items, function (filter) {
Ext.Object.each(me.tree.nodeHash, function (key, node) {
if (filter.filterFn) {
if (!filter.filterFn(node)) node.remove();
} else {
if (node.data[filter.property] != filter.value) node.remove();
}
});
});
me.hasFilter = true;
console.log(me);
},
clearFilter: function() {
var me = this;
me.filters.clear();
me.hasFilter = false;
me.load();
},
isFiltered: function() {
return this.hasFilter;
},
filterNavAdminSTByUserName: function (nameValue) {
this.clearFilter();
this.filter([{
property: 'userName',
value: nameValue
}]);
}
My problem is that this.filter() gets executed before this.clearFilter(); How do I force this.filter() to execute only after this.clearFilter() completes?
Thanks in advance!
After some soul searching I've finally figured out how callback functions work.
So here is the solution:
clearAndFilter: function (nameValue) {
var me = this;
me.filters.clear();
me.hasFilter = false;
me.load({
scope: me,
callback: function () {
// filter the store
me.filter('userName', nameValue);
}
});
},
filterNavAdminSTByUserName: function (nameValue) {
this.clearAndFilter(nameValue);
}
Feels good to answer to my first ever post here!
I should run multiple ajax requests in one button click, but all requests should wait until the first one is executed. I have tried to put all requests in the success callback of the first one but this gives this error:
TypeError: o is undefined
return o.id;
And just the first request is executed.
This is my code:
if(form1.isValid()) {
form1.submit(me._genFormSubmitAction('my_DB','my_Action', function() {
console.log('form1 success');
//Submit Form2
if(form2.isValid()) {
form2.submit(me._genFormSubmitAction('my_DB','my_Action', function() {
console.log('form2 success');
}));
//Submit Form3
....
_genFormSubmitAction:
_genFormSubmitAction: function(db,action, successCallback) {
var me = this;
return {
clientValidation : true,
url : me.getApplication().apiUrl,
waitMsg : '<p align=right>..الرجاء الإنتظار</p>',
async:false,
params : {
_module: 'administrationcassocial',
_action: action,
_db:db
},
success : function(form, action) {
if(action.result.success == true) {
Ext.callback(successCallback, me);
form.owner.destroy();
} else {
console.log('url=',url);
Ext.Msg.alert(action.result.error, action.result.errormessages.join("\n"));
}
},
failure : function(form, action) {
switch (action.failureType) {
case Ext.form.action.Action.CLIENT_INVALID:
Ext.Msg.alert('Failure', 'Form fields may not be submitted with invalid values');
break;
case Ext.form.action.Action.CONNECT_FAILURE:
Ext.Msg.alert('Failure', 'Ajax communication failed');
break;
case Ext.form.action.Action.SERVER_INVALID:
Ext.Msg.alert(action.result.error, action.result.errormessages.join("\n"));
}
}
};
}
This is a scope issue.
The callback of form1.submit happens in the callback own scope, so it has no idea what form2 is.
You can try:
if(form1.isValid()) {
var me = this;
form1.submit(me._genFormSubmitAction('my_DB','my_Action', function() {
console.log('form1 success');
//Submit Form2
if( me.form2.isValid() ) {
form2.submit(me._genFormSubmitAction('my_DB','my_Action', function() {
console.log('form2 success');
}));
}
}));
}
Or the more proper solution in my view:
// Added aScope var
_genFormSubmitAction: function( db,action, aScope, successCallback ) {
var me = this;
return {
// ...
scope: aScope
}
}
Then you call:
form1.submit(me._genFormSubmitAction('my_DB','my_Action', this, function() {
}));
I want to migrate the javascript in my site from YU2 to YUI3, but I am only a poor amateur programer and I am stuck at the first pitfall.
I have the following code:
MyApp.Core = function() {
return {
init: function(e, MyAppConfig) {
if (MyAppConfig.tabpanels) {
MyApp.Core.prepareTabpanels(MyAppConfig.tabpanels);
}
},
prepareTabpanels: function(tabpanels) {
// Code here
}
}
}();
var MyAppConfig = {
"tabpanels":{"ids":["navigation"]}
};
YAHOO.util.Event.addListener(window, "load", MyApp.Core.init, MyAppConfig);
How can I pass the MyAppConfig object to the MyApp.Core.init function by using YUI3 "domready" event listener?
Thanks in advance!
You should be able to do something like:
var MyApp = {};
MyApp.Core = function(){ return {
init: function(MyAppConfig) {
console.log(MyAppConfig);
},
prepareTabpanels: function(tabpanels) {
// Code here
}
}
}();
var MyAppConfig = {
"tabpanels":{"ids":["navigation"]}
};
YUI().use('node', 'event', function(Y){
Y.on('domready', MyApp.Core.init, this, MyAppConfig);
});
Note that the event is not passed in as the first parameter, it is the config.
Y.on accepts parameters as <event_type>, <callback_function>, <context>, <params>..
any parameter after the third item is passed through to the callback function so MyAppConfig becomes the first parameter in your init.
EDIT
See the YUI3 API documentation here: http://developer.yahoo.com/yui/3/api/YUI.html#method_on
