我在堆棧溢出上使用了一個示例here來創建自定義驗證文本區域小部件。我遇到的問題是小部件不會接受返回有效字符。有什麼我可以做的,以允許退貨?無論何時在窗口小部件中輸入回車,控件都會顯示紅色的無效指示符和'輸入的值無效'的消息。我使用的代碼如下:返回字符對於SimpleText區域和驗證文本框的混入無效
自定義部件:
define(["dojo/_base/declare", "dojo/_base/lang", "dijit/form/SimpleTextarea", "dijit/form/ValidationTextBox"],
function (declare, lang, SimpleTextarea, ValidationTextBox) {
return declare('dijit.form.ValidationTextArea', [SimpleTextarea, ValidationTextBox], {
constructor: function (params) {
this.constraints = {};
this.baseClass += ' dijitValidationTextArea';
},
templateString: "<textarea ${!nameAttrSetting} data-dojo-attach-point='focusNode,containerNode,textbox' autocomplete='off' placeHolder='${placeHolder}'></textarea>"
})
})
標記:
<textarea data-dojo-type="Scripts/ValidationTextArea"
data-dojo-attach-point="taGoalsObjectives" style="width:425px; height:75px"
required='true'
placeHolder="max 2000 characters"
data-dojo-props="trim:true,maxLength:'2000'"></textarea>
