How can I mimic text-overflow: ellipsis in Firefox?

阅读更多关于 How can I mimic text-overflow: ellipsis in Firefox?

问题 I have some dynamic text contained in a div that is set to whatever a user enters in a textbox field. If the text doesn't fit in the div, right now it just gets cut off at the edge and all the text that extends past the border is not visible. I would like to truncate the text so that it fits inside the box and has an ellipsis (...) appended on the end. For example: |----div width------| Here is some sample text that is too long. Here is some sam... Obviously in the example it's easy because

How do I check if a char is a vowel?

阅读更多关于 How do I check if a char is a vowel?

This Java code is giving me trouble: String word = <Uses an input> int y = 3; char z; do { z = word.charAt(y); if (z!='a' || z!='e' || z!='i' || z!='o' || z!='u')) { for (int i = 0; i==y; i++) { wordT = wordT + word.charAt(i); } break; } } while(true); I want to check if the third letter of word is a non-vowel, and if it is I want it to return the non-vowel and any characters preceding it. If it is a vowel, it checks the next letter in the string, if it's also a vowel then it checks the next one until it finds a non-vowel. Example: word = Jaemeas then wordT must = Jaem Example 2: word=Jaeoimus

Why is T-SQL ISNULL() truncating the string and COALESCE is not?

阅读更多关于 Why is T-SQL ISNULL() truncating the string and COALESCE is not?

问题 Given the following: SELECT ISNULL('XY' + NULL, 'ABCDEFGHIJ') -- Outputs ABC (Why?) SELECT COALESCE('XY' + NULL, 'ABCDEFGHIJ') -- Outputs ABCDEFGHIJ Why are these statements returning different results? 回答1: According to Microsoft documentation, for function: ISNULL(check_expression, replacement_value) replacement_value must be of a type that is implicitly convertible to the type of check_expression . Note that type for 'xy'+NULL is VARCHAR(3) . Because of this your string 'ABCDEFGHIJ' is

Ellipsis in the middle of a text (Mac style)

阅读更多关于 Ellipsis in the middle of a text (Mac style)

I need to implement ellipsis ( "..." ) in the middle of a text within a resizable element. Here is what it might look like. So, "Lorem ipsum dolor sit amet. Ut ornare dignissim ligula sed commodo." becomes "Lorem ipsum dolor sit amet ... commodo." When the element is stretched out to the width of the text, I want the ellipsis to disappear. How can this be done? Stefan Lundström In the HTML, put the full value in a custom data-* attribute like <span data-original="your string here"></span> Then assign load and resize event listeners to a JavaScript function which will read the original data

PHP is truncating MSSQL Blob data (4096b), even after setting INI values. Am I missing one?

阅读更多关于 PHP is truncating MSSQL Blob data (4096b), even after setting INI values. Am I missing one?

问题 I am writing a PHP script that goes through a table and extracts the varbinary(max) blob data from each record into an external file. The code is working perfectly (I used virtually the same code to go through some images) except when a file is over 4096b - the data is truncated at exactly 4096. I've modified the values for mssql.textlimit , mssql.textsize , and odbc.defaultlrl without any success. Am I missing something here? <?php ini_set("mssql.textlimit" , "2147483647"); ini_set("mssql

Truncated Data when Importing from Excel to an Access Memo Field

阅读更多关于 Truncated Data when Importing from Excel to an Access Memo Field

问题 Access is truncating the data in a couple Memo fields when I am appending an Excel file. The field in the Access table is already set as a Memo type. I believe the problem is that I do not have any entries in the first few rows of some of the memo fields. Access is assuming the data is a text field, even though I have already set it as a Memo type. I have tried appending as a CSV. Did not work. I have put dummy data in the first row that exceeds the 255 character limit and the data is not

SQL Server silently truncates varchar's in stored procedures

阅读更多关于 SQL Server silently truncates varchar's in stored procedures

According to this forum discussion , SQL Server (I'm using 2005 but I gather this also applies to 2000 and 2008) silently truncates any varchar s you specify as stored procedure parameters to the length of the varchar, even if inserting that string directly using an INSERT would actually cause an error. eg. If I create this table: CREATE TABLE testTable( [testStringField] [nvarchar](5) NOT NULL ) then when I execute the following: INSERT INTO testTable(testStringField) VALUES(N'string which is too long') I get an error: String or binary data would be truncated. The statement has been

SQL Server truncation and 8192 limitation

阅读更多关于 SQL Server truncation and 8192 limitation

In SQL Server 2005 I am trying to query a varchar(MAX) column which has some rows with text data that exceed the 8192. Yet, In Management Studio I have under Tools --> Options --> Query Results --> Results to Text --> Max numbers of characters displayed in each column = 8192 , which is a maximum. Accordingly, it seems the truncation on these rows occurs only due to the limitation imposed by text output. The only thing I see to get around this is to use a SUBSTRING function to grab say the first 8000 chars, then the next 8000 chars etc. etc. But this is ugly and error prone. I should mention
