ExtJS provides us with a complete form verification function, so that we can easily achieve a variety of form field verification, which is a little more complex password verification, today, Lee Bad on ExtJS password verification function for everyone to provide a simple demo, I hope to help.

The code is as follows

Copy Code

Ext.application ({ Name: ' Demo ', Appfolder: ' App ', Launch:function () { Ext.create (' Ext.container.Viewport ', { Margin: ' 100 0 0 200 ', items:[{ Xtype: ' Form ', Title: ' Password verification ', HEIGHT:500, width:700, defaults:{ Xtype: ' TextField ', WIDTH:300, Labelwidth:60, Margin: ' 20 0 0 200 ', InputType: ' Password ', Allowblank:false, Msgtarget: ' under ' }, items:[{ Fieldlabel: ' Enter password ', Regex:/^ ([A-za-z0-9]{6,}) $/i, Regextext: ' Password must contain both letters and numbers, with at least 6 digits ' },{ Fieldlabel: ' Enter again ', Validator:function (value) { var pw = this.previoussibling (). value; if (value!= pw) { Return ' two input passwords inconsistent '; }else{ return true; } } }] }] }); } });
