Question

我在我的项目中使用primefaces 3.0，我已经在testing1.xhtml中实现了图表，但该页面内容需要显示在main.xhtml上，但图表不是第一次呈现。仅提供刷新后的图表渲染，但它不应该像这样..我已附加模型片段供您参考..请帮助我解决此问题..

testing1.xhtml

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:p="http://primefaces.prime.com.tr/ui"
      xmlns:a4j="http://richfaces.org/a4j"
      xmlns:rich="http://richfaces.org/rich"
       xmlns:portlet="http://java.sun.com/portlet"
      xmlns:c="http://java.sun.com/jstl/core">

      <h:form id="testForm">

      <p:lineChart id="testChart"  value="#{testBean.chart}"
      style="float:left; margin-top:150px; border:0px; margin-left:0px; padding:0px; height:140px; width:230px; "/> 
    <h:form>

</ui:composition>

我从main.xhtml调用此页面

main.xhtml

    <body onLoad="loadData();" >

        <h:panelGrid style="height:33px;"/>
        <h:form style="margin:0px; padding:0px;">
    <p:remoteCommand name="loadData" action="#{testBean.chartLoad}"  update="testChart" />

 <p:panel  style="height:auto; width:238px;" id="testPanel" header="Testing" closable="false" toggleable="true">
              <ui:include src="testing1.xhtml"/>
            </p:panel>

提前感谢..

Answer 1

看起来看起来是一个嵌套的form问题......

尝试从内页中移除<h:form id="testForm">，导致其已被外页的form标记包围...

Answer 2

只需在页面中添加这些行。加载js / css

时出错

System.out.print("Input Equation : ");
                    n = s.next() + s.nextLine();

                    n = n.replaceAll("\\s+", "");

                    char[] nans = n.toCharArray();

                    c = 0;
                    for (int i = 0; i < n.length(); i++) 
                        if (nans[i] == '+' || nans[i] == '-' || nans[i] == '/' || nans[i] == '*') 
                            c++;

                    char[] op = new char[c];
                    int[] num = new int[c + 1];

                    c = 0;
                    for (int i = 0; i < n.length(); i++) {
                        if (nans[i] == '+' || nans[i] == '-' || nans[i] == '/' || nans[i] == '*') {
                            op[c] = nans[i];
                            c++;
                        }
                    }

                    c = 0;
                    for (int i = 0; i < n.length(); i++) {

                        if (nans[i] == '1' || nans[i] == '2' || nans[i] == '3' || nans[i] == '4' || nans[i] == '5' 
                         || nans[i] == '6' || nans[i] == '7' || nans[i] == '8' || nans[i] == '9' || nans[i] == '0') 
                        nus = nus + nans[i]; 

                        else if (nans[i] == '+' || nans[i] == '-' || nans[i] == '/' || nans[i] == '*') {
                            num[c] = Integer.parseInt(nus);
                            nus = "";
                            c++;
                        }
                        if (i == n.length() - 1){
                            num[c] = Integer.parseInt(nus);
                        }
                    }

                    for (int i = 0; i < c; i++) {
                        if (op[i] == '+') {
                            result = result + num[i] + num[i + 1];
                            num[i + 1] = 0;
                        }

                        else if (op[i] == '-') {
                            result = result + num[i] - num[i + 1];
                            num[i + 1] = 0;
                        }

                        else if (op[i] == '/') {
                            result = (result + num[i]) / num[i + 1];
                            num[i + 1] = 0;
                        }

                        else if (op[i] == '*') {
                            result = (result + num[i]) * num[i + 1];
                            num[i + 1] = 0;
                        }
                    }



                    System.out.print(" = "+ result);

从testing1.xhtml中删除标记。由于您的主页面包含h：表单标记，因此您无需在您的ui：include中添加其他标记。

即使它不起作用，然后添加ID并添加update =＆＃34;：＆lt; yourGivenFormID＆gt;＆＃34;在p：lineChart

Answer 4

删除testing1.xhtml中的表单标记

在tests1.xhtml页面的head部分添加以下内容：

<h:head>
    <link rel="stylesheet" href="/javax.faces.resource/charts/charts.css.jsf?ln=primefaces"/>
    ......
</h:head>
