Ecology8二次开发：HTML表单字段必填验证的添加与移除

/**
* 给字段添加必填验证。
*/
var addInputCheckField = function(fieldId, spanImgId) {
$('#' + fieldId).attr('viewtype', '1');
var fieldStr = $('input[name=needcheck]').val();
if (fieldStr.charAt(fieldStr.length - 1) != ',') {
fieldStr += ',';
}
$('input[name=needcheck]').val(fieldStr + fieldId + ',');
$('#' + spanImgId).html('<img src="/images/BacoError_wev8.gif" align="absMiddle">');
};

/**
* 移除字段必填验证。
*/
var removeInputCheckField = function(fieldId, spanImgId) {
$('#' + fieldId).attr('viewtype', '0');
var fieldStr = $('input[name=needcheck]').val();
$('input[name=needcheck]').val(fieldStr.replace(fieldId + ',', ''));
$('#' + spanImgId).html('');
};

// 调用移除必填验证函数
removeInputCheckField('field10391', 'field10391span');	// 移除必填验证，主表文本框、选择框
removeInputCheckField('field10849', 'field10849spanimg');	// 移除必填验证，主表浏览框
removeInputCheckField('field10859_0', 'field10859_0span');	// 移除必填验证，明细表文本框、选择框
removeInputCheckField('field10859_0', 'field10859_0spanimg');	// 移除必填验证，明细表浏览框

// 调用添加必填验证函数
addInputCheckField('field10391', 'field10391span');	// 添加必填验证，主表文本框、选择框
addInputCheckField('field10849', 'field10849spanimg');	// 添加必填验证，主表浏览框
addInputCheckField('field10859_0', 'field10859_0span');	// 添加必填验证，明细表文本框、选择框
