[Original] summarizes the reusable functions of this project.

This. Net project is coming to an end. I want to extract public reusable functions. One is to share with you, and the other is to accumulate my own experience.

 

First, share a Javascript file named config. JS, which is put under the project and can be used for the entire project.

 

The Code is as follows:

 

// Shield the right-click menu. This is very important for a professional system </P> <p> document. oncontextmenu = function () {return false ;}</P> <p> // The textcounter function calculates the number of digits that the current user can enter based on the characters entered by the user, </P> <p> // It is user-friendly in terms of customer experience, when the number of words exceeds the limit, the corresponding words are automatically intercepted. </P> <p> // here, field is the textbox that allows the user to input data; maxlimit is the maximum number of words that can be entered </P> <p> // labelstr is a label or Textbox, which displays the number of words that can be entered dynamically, </P> <p> // we recommend that you set it to // read-only </P> <p> function textcounter1 (field, maxlimit, labelstr) </P> <p >{</P> <p> If (document. getelementbyid (F Ield ). value. length> maxlimit) </P> <p >{</P> <p> document. getelementbyid (field ). value = document. getelementbyid (field ). value. substring (0, maxlimit); </P> <p >}</P> <p> else </P> <p >{</P> <p> document. getelementbyid (labelstr ). value = maxlimit-document. getelementbyid (field ). value. length; </P> <p >}</P> <p> // calculate the number of characters in the textbox, overload of the above function </P> <p> function textcounter (field, maxlimit) </P> <p >{</P> <p> If (document. getelementbyid (field ). value. length> maxlimit) </P> <p >{</P> <p> document. getelementbyid (field ). value = document. getelementbyid (field ). value. substring (0, maxlimit); </P> <p >}</P> <p> else </P> <p >{</P> <p> document. getelementbyid ("remlen "). value = maxlimit-document. getelementbyid (field ). value. length; </P> <p >}</P> <p> // a small window is displayed, and the address bar, menu bar, the status bar is blocked, and the window size is also required. <br/> functio N dblclickfunc () {<br/> window. open ("messageemp. aspx "," newwindow "," Height = 500, width = 650, Top = 100, Left = 220, toolbar = No, menubar = No, scrollbars = No, resizable = Yes, location = No, status = No "); <br/>}</P> <p> // select all check boxes <br/> function selectall (OBJ) <br/>{< br/> var thetable = obj. parentelement. parentelement. parentelement. parentelement; <br/> var I; <br/> var J = obj. parentelement. cellindex; </P> <p> F Or (I = 0; I <thetable. rows. length; I ++) <br/>{< br/> var objcheckbox = thetable. rows [I]. cells [J]. firstchild; <br/> If (objcheckbox. checked! = NULL) objcheckbox. checked = obj. checked; </P> <p >}< br/>}</P> <p> // select the value of the row selected by the checkbox <br/> function checkchanginfo () <br/>{< br/> var I; <br/> for (I = 0; I <document. all. gvgoodsclassinfo. rows. length; I ++) <br/>{< br/> var cb = document. all. gvgoodsclassinfo. rows (I ). cells (0 ). children (0); </P> <p> If (CB. checked) <br/>{< br/> document. getelementbyid ("txtmodel "). value = document. all. gvgoodsclassinfo. rows (I ). cells (1 ). innertext; <br/> document. getelementbyid ("txtremark "). value = document. all. gvgoodsclassinfo. rows (I ). cells (2 ). innertext; <br/>}< br/>
