ex: 67278 how can using preg_match??? how can information preg_match? $data = '<script>fcgetplayerinsights("67278")</script>)'; preg_match("/tr\('(.*?)'/",$data,$match); print_r($match); i not recommend regex on html unless it's way... but: if(preg_match("/(\d{5})/", $data)){ echo "a 5 digit number there"; }else{ echo "there no 5 digit number"; } may work.. recommend @ least use strip_tags on $data. if(preg_match("/(\d{5})/", strip_tags($data))){ echo "a 5 digit number there"; }else{ echo "there no 5 digit number"; } that removes html string , leaves fcgetplayerinsights("67278")) to regex on, bit safer. http://www.phpliveregex.com/p/hno

javascript - How to prevent a click from passing through a fixed positioned element to the element behind it? -

i have fixed positioned header has searchbox in , there content behind (the header has higher z-index). have event handler handles 'focus' event on searchbox. problem when click in searchbox, event handler triggers, click passes through header elements behind it. don't want click pass through. tried event.preventdefault() , event.stoppropagating() , event.cancelbubble = true none of them seems work. it looks you're trying stop propagation of focus event. try binding click event of searchbox , use event.stoppropagation() on it.

python - Dynamically creating models in Django -

i want create many models based on abstract one, different default values fields. def get_model(name): class abstractmodel(models.model): field1 = models.charfield(max_length=100, default=name) class meta: abstract = true return abstractmodel class mymodel(get_model('mymodel')): pass what disadvantages of approach presented above? there better way? it looks need single model instead of set of models. might have single model additional field having kind of model type - same model name. there lots of disadvantages of idea. confusing others , influence negatively performance due constant using code reflections. update default value name dependent on class can make overwriting in constructor: from django.db import models class a(models.model): def __init__(self): self.f = 'model name' f = models.charfield(max_length=100) class b(a): def __init__(self): self.f = 'model b n

android - How to read files located on values folder -

this question has answer here: how string different locales in android? 3 answers i read string.xml file, in full, located under : src -> main -> res -> values. for sake of argument, need specific file in order handle localization issues might occur in application : selected device language french, still, want values main english string.xml file only specific scenarios . so, resources in values/strings.xml should exists on values-fr/strings.xml, , removing them values-fr is not option . obviously, solution of sort of getstring(r.string.text_name) not acceptable since we'll receive value of text_name values-fr/strings.xml file, , not values/strings.xml . this won't : getresources().getidentifier("text_name", "string", getpackagename()); this won't well, since string.xml not raw asset. context.getresources().openra
