search

问题 I have set up a search in uiwebview with javascript that works great, but I want to be able to jump to the next found word in the search results. I have succeeded in geting the view to scroll to the first instance by using this code: if (uiWebview_SearchResultCount == 1) { var desiredHeight = span.offsetTop - 140; window.scrollTo(0,desiredHeight); } How can I get this searchresultcount to update to the next found result(say 2, 3, 4, 5, ect...) when user presses button in app?? Thanks in

问题 For simplicity sake, suppose I have the graph: O O P O | O O O O O O | O | O O O O O O A O O O O In which I want to use a breadth-first search to travel from A to P by the shortest path, where positions designated by | are restricted areas. How can I achieve this result? I've always seen the breadth-first search used to find some location (P in this case), but I haven't seen any implementation used to store path distances and compute the shortest one (nor efficient methods to store previously

问题 Is there a way to remove an item from a listbox based on a string? I have been playing around for a few minutes and here is what i have so far but its not working foreach(string file in LB_upload.Items) { ftp.Upload(file); int x = LB_upload.Items.IndexOf(file); LB_upload.Items.RemoveAt(x); } I could just loop through each item but I wanted to do something a little more elegant 回答1: while(LB_upload.Items.Count > 0) { ftp.Upload(LB_upload.Items[0].ToString()); LB_upload.Items.RemoveAt(0); } 回答2

问题 I am doing a project where I want a person to enter the name of any artist/band into a text box where it will seach my mysql database for the event information and display the results/content on another page. The code below is within my index.php where it should get the information from search.php (below also). I've looked all over and I'm not sure why it's not working and I can't figure out what to do. Help would be great! (I really need to pass this class!) :) (index.php) <form name="search

问题 I am creating a search function of my classifieds on my website. Here is some of the criteria I need to meet: When searching for 'bmw 520' only matches where these two words come in exactly this order is returned. not matches for only 'bmw' or only '520'.

I want the 'minus sign' to 'exclude' all returns

问题 An activity is supposed to be able to provide context information to a content provider like this: @Override public boolean onSearchRequested() { Bundle appSearchData = new Bundle(); appSearchData.putByte("category", category); startSearch(null, false, appSearchData, false); return true; } Search suggestions and results from the provider should be limited to 'category', but I can't find where to access the appSearchData bundle from my ContentProvider. 回答1: Use this for onSearchRequested:

问题 I have a simple address book app that I want to make searchable. The model would look something like: class Address(models.Model): address1 = models.CharField("Address Line 1", max_length=128) address2 = models.CharField("Address Line 2", max_length=128) city = models.CharField("City", max_length=128) state = models.CharField("State", max_length=24) zipCode = models.CharField("Zip Code", max_length=24) def __unicode__(self): return "%s %s, %s, %s, %s" % (self.address1, self.address2, self

问题 Using only pseudo-code or JavaScript, can anyone describe the best way to determine which items in array of objects composed of: { "lat": float, "lng": float } are within a given radius in either miles or kilometers? I am adding geo-location-based queries to ForerunnerDB (https://github.com/irrelon/ForerunnerDB) and would like to be able to produce fast results from the search. Bonus points if you can describe an indexing strategy that will speed up the query over the array. I have written
