javascript - Visualforce で Jquery が期待どおりに動作しない

Question

動的コンポーネントを使用している Visualforce を作成しています。私の Visualforce コードは次のとおりです。

<apex:page title="Salesforce SOQL Offset Example Using Visualforce" standardStylesheets="false" controller="dynamic_visualforce_with_soql_offset" sidebar="false" readOnly="true" cache="false" showHeader="false" >

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.1/jquery-ui.min.js"></script>

<script type="text/javascript">
$(function(){

$("[id$=prev]").click(function(){alert('Hello World');});

});
</script>


<apex:sectionHeader subtitle="SOQL Offset Example w/Dynamic Page Buttons" title="Square Root Table"/>

<apex:form >

<apex:pageBlock >   

    <apex:actionFunction action="{!refreshGrid}" name="queryByPage" reRender="myPanel,myButtons" >
        <apex:param name="firstParam" assignTo="{!selectedPage}" value="" />
    </apex:actionFunction>

    <apex:dynamicComponent componentValue="{!myCommandButtons}"/>        

    <apex:pageBlockSection title="Numbers and their Square Roots (Total List Size: {!total_size})" collapsible="false">

    <apex:outputPanel id="myPanel">

    <apex:pageMessages id="theMessages" />

    <apex:pageBlockTable value="{!numbers}" var="n" align="center">

        <apex:column value="{!n.Id}" />

        <apex:column value="{!n.Name}" />

        <apex:facet name="footer">Showing Page # {!pageNumber} of {!totalPages}</apex:facet>

    </apex:pageBlockTable>

    }    

しかし、前のボタンをクリックしようとすると、jquery関数から期待されているアラートが表示されず、htmlコードが

前のボタンを押してもアラートが表示されない理由を教えてください

Answer 1

force.com は、prototype.js などの js ライブラリを使用しており、jQuery と競合する可能性があります。回避するには、この記事http://api.jquery.com/jQuery.noConflict/を参照してください。

次のトリックを使用します

<script>
 window.$j = jQuery.noConflict();

$j(function(){
    $j("[id$=prev]").click(function(){alert('Hello World');});

});

</script>
