Netsuite 中 js 扫描枪应用 解读一

货品编码不是动态去货品那里每次扫描去查询的，而在加载单据时，那么货品码早就在那里等待匹配了。这样效率就能有保证。 12:13 2010-03-03

onblur

<input type="text" id="item_autoenter" onblur="if (this.checkvalid == true) {this.isvalid=validate_field(this,'text',false,false);} if (this.isvalid == false) { selectAndFocusField(this); return this.isvalid;}" name="item_autoenter" size="15" onfocus="if (this.isvalid == true || this.isvalid == false) this.checkvalid=true;" onchange="setWindowChanged(window, true);this.isvalid=validate_field(this,'text',true,false);this.checkvalid=false;if (this.isvalid) {if (value.length > 0) {itemLocateField(value); value='';};}if (this.isvalid) this.isvalid=validate_textfield_maxlen(this,60,true,true);if (!this.isvalid) { selectAndFocusField(this);}return this.isvalid;" class="input" onkeypress="if( getEventKeypress(event) == 13) { event.cancelBubble = true; if (value.length > 0) {itemLocateField(value); value=''; } else {NLDoMainFormButtonAction('submitter');} return false;}" maxlength="60"/>

event.cancelBubble = true 用来阻止enter键向父级传递（导致系统会认为要保存单据了），itemLocateField(value); 是回车以后查询扫描码的事件。
